My volleyball got very weighted, it soaked in water bcz kf rain previously, now it's very heavy, despite being high quality ball. I tried sun dry..it only reduced weight a bit..what can i do? What would you do?

GLM-5.2 (changed mind)

Answer: First deflate the ball and squeeze trapped water out through the inflation valve, then dry it slowly using airflow and a desiccant environment rather than direct heat.

My original answer covered gentle heat, airflow, and desiccants, but it missed a key step that Claude Opus 4.8 highlighted: actively removing water through the inflation valve. If the ball is noticeably heavy, water is likely trapped inside the bladder or between the bladder and cover, and passive evaporation alone — even with silica gel or rice — can take a very long time because the moisture has to work back out through the seams. By deflating the ball completely, holding it valve-down, and gently pressing/rolling it, much of that trapped water can be expelled directly through the valve. After that, the desiccant + airflow method I originally proposed becomes far more effective at pulling out the remaining moisture. I'm also persuaded by GPT-5.5's practical advice to shake the ball and listen for sloshing first, and to weigh it against the normal 260–280g range to judge whether the drying has actually worked. Combining valve-draining with a patient desiccant drying process — while avoiding harsh heat, ovens, or hair dryers on high — is the most complete and safest approach.

Answer: I’ll stick with my sealed-bag desiccant method but add the valve-drain step from Claude, and I’ll only consider replacing the ball if the weight doesn’t return to ~260–280 g after about a week.

Reviewing the other answers, I think Claude Opus 4.8 made the most overlooked and important point: a lot of the excess weight may not just be moisture trapped in the foam/padding layers — it may literally be water sitting *inside* the rubber bladder that got in through the valve or a seam. If that’s the case, no amount of silica gel or airflow will pull water out of a sealed rubber bladder; it has to come out through the valve. That step is missing from my original answer and from Gemini’s and Qwen’s answers. So I’m updating my approach to combine techniques instead of relying on only one. Here’s what I’d actually do, in order, drawing from the best parts of all the models: 1. **Check first, don’t just start drying.** Weigh the ball on a kitchen scale. A standard volleyball is ~260–280 g. Feel the ball and shake it gently near your ear — if you hear sloshing, water is almost certainly inside the bladder (Claude and GPT-5.5 both flagged this, and it’s the key diagnostic step I missed). 2. **Drain through the valve first (the Claude step that changed my mind).** Moisten a pump needle with saliva or soapy water, fully deflate the ball, hold it valve-side-down, and gently squeeze/roll it. Water will slowly drip out. Repeat, rotating the ball, until no more water comes out. This handles the bladder-water case that desiccants alone cannot fix. 3. **Then the desiccant method (Gemini + my original answer).** Put the drained ball in a sealed zip-lock or trash bag along with lots of silica gel packets or a few pounds of dry uncooked rice. Leave it 3–7 days in a warm, dry room. This pulls the moisture that’s still trapped in the foam backing and between the cover panels — the part sun-drying can’t reach. 4. **Add gentle airflow in parallel (Qwen’s good point).** A fan or a dehumidifier running in the same room speeds things up and prevents moisture from re-condensing. 5. **Strictly avoid direct heat** (everyone agreed, and this is important): no hair dryer, no oven, no prolonged harsh midday sun. Heat damages the bladder, weakens panel glue, and cracks the composite cover. I’ll retract my original suggestion of a low-heat hair dryer because the risk isn’t worth it — desiccants + airflow + valve draining handle the same job more safely. 6. **Rotate the ball every few hours** (Qwen) so water doesn’t pool on one side and deform the shape. 7. **Re-inflate and reweigh after ~5–7 days.** If it’s back to ~260–280 g and feels normal, great. If it’s still significantly heavier, feels lumpy, dead, or unbalanced, the inner layers are probably permanently saturated — I agree with GPT-5.5 that at that point the honest answer is to stop using it for serious play (a heavy ball wrecks shoulders and fingers) and replace it. I’d also contact the seller if it’s new, because a quality ball shouldn’t absorb water this badly. ### Why I changed my position My round-1 answer leaned almost entirely on desiccants and didn’t tell the user to check whether water was actually *inside the bladder*. Claude’s “deflate, squeeze it out through the valve” step is genuinely the missing piece — and Gemini’s sealed-bag desiccant method is the safest follow-up for moisture in the foam layers. Combining them covers both possible locations of the water, which neither answer did alone. I’m not fully convinced by GPT-5.5’s “just replace it” framing as a first move because most waterlogged balls can be restored, but I agree it’s the right call if drying fails after a week.

Claude Opus 4.8 (changed mind)

Answer: Get trapped water out through the valve by deflating and gently squeezing, then use the desiccant (silica gel/rice in a sealed bag) plus gentle airflow method to draw out deep moisture — and retire the ball for play if it's still heavy after a week.

After reading the other responses, I'm strengthening and revising my answer. My original valve-squeeze step is still correct for water that reached the bladder, but the other models made an important point I underweighted: in a high-quality ball, much of the trapped water is likely sitting in the foam/backing layers between the cover panels and the bladder — not just inside the bladder. That water cannot be squeezed out through the valve at all, which explains why sun-drying and squeezing only help a little. The desiccant method — sealing the ball in an airtight bag with lots of silica gel or dry uncooked rice for several days — is the piece I was missing, and nearly every other model independently converged on it. That's compelling. A sealed dry microclimate slowly pulls moisture out of the internal foam layers through the seams without any heat, which is exactly what those inaccessible layers need. So my refined plan: (1) First do the valve step — deflate, hold valve-down, gently squeeze and roll to expel any liquid water inside the bladder (do this only if you hear sloshing). (2) Wipe the surface dry. (3) Put the ball in a sealed bag/box packed with silica gel or rice for 3–7 days, rotating it daily, ideally near a fan in a warm dry room. (4) Avoid harsh direct sun, hair dryers on high, and ovens, since heat degrades the panel glue and bladder. One more point GPT-5.5 pro raised that I fully agree with: know when to stop. A normal volleyball is about 260–280 g. If after a week it's still noticeably heavy, dead, or lumpy, the inner layers are permanently waterlogged, there's no reliable home fix, and playing with a heavy ball risks finger and wrist injury — so replace it, and use a rubber/outdoor ball in the rain next time.

Gemini 3.1 Pro Preview (changed mind)

Answer: I would first insert a lubricated ball needle to deflate and squeeze out any water trapped inside the bladder, then place the ball in an airtight bag with a strong desiccant to draw out the remaining moisture.

I previously focused solely on using a desiccant microclimate to draw out moisture. However, "Claude Opus 4.8" correctly pointed out that if the ball is significantly heavier, a large amount of water may have bypassed the outer panels and pooled inside the inner bladder. Evaporating trapped liquid water from inside a rubber bladder using only desiccants would take an agonizingly long time. The most logical approach is a two-step process. First, you must mechanically drain the ball. By inserting a lubricated ball needle to hold the valve open, flipping the ball valve-side down, and gently pressing, you can physically force out the bulk of the liquid water. Once the liquid water is expelled, my original desiccant method becomes much more practical and effective. You can then partially re-inflate the ball so it holds its shape, place it in an airtight bag surrounded by silica gel, and let the desiccant safely draw out the residual moisture deeply embedded in the inner foam without risking heat damage.

Qwen3.7-Max (changed mind)

Answer: I now believe the most effective approach is to first actively drain any trapped water through the inflation valve by deflating and squeezing the ball, and then use a sealed desiccant chamber with silica gel to draw out remaining moisture from the outer layers.

In my previous response, I focused primarily on ambient airflow and dehumidifiers, treating the possibility of water inside the internal bladder as a secondary scenario. However, Claude Opus 4.8 convincingly argued that an excessively heavy, rain-soaked ball likely has water directly inside the bladder, meaning surface drying or ambient airflow will be entirely ineffective for removing the bulk of the trapped liquid. Actively deflating the ball, holding it valve-down, and physically squeezing the water out is a crucial mechanical first step that I underemphasized. Furthermore, incorporating the desiccant method—sealing the ball in an airtight bag with abundant silica gel—creates a much more aggressive low-humidity microclimate to pull moisture out of the foam backing and composite leather than a standard fan in a room. By combining the valve-draining technique to remove the bulk liquid with a desiccant chamber to extract the deeply embedded dampness, while strictly avoiding direct heat that could melt adhesives, you give the ball the best chance of recovery. Finally, weighing the ball afterward to ensure it has returned to the standard 260–280g range is essential, as playing with a heavy, waterlogged ball can cause serious finger and wrist injuries.

GPT-5.5 pro

Answer: I’d still try one gentle valve-check plus slow airflow/desiccant drying process, but if the ball stays clearly heavier than a normal 260–280 g volleyball after about a week, I’d stop using it for real play and replace it.

I’m maintaining my position: the other answers mostly reinforce it rather than change it. The useful shared point from GLM-5.2, Gemini 3.1 Pro Preview, and Qwen3.7-Max is that sun only dries the surface, while trapped water in foam/fabric layers needs moving dry air and/or desiccant; I agree. Claude Opus 4.8’s valve-draining idea is also worth trying, but mainly if you hear sloshing or suspect water is inside the bladder. MiniMax M3’s idea of removing the cover is not something I’d try unless the ball is specifically designed to be disassembled, because most volleyballs are glued/stitched and you can ruin them. What I would do now: weigh it if you can. Normal competition volleyballs are roughly 260–280 g. Insert a moistened/lubricated inflation needle, hold the valve downward, and gently squeeze/roll the ball only if you hear or feel water inside; do not puncture anything or force it. Then inflate it to normal or slightly under normal pressure so it keeps its shape, wipe it dry, and leave it indoors in shade with a fan and, ideally, a dehumidifier. Rotate it often. For deeper drying, put it in a sealed box or bag with lots of silica gel or a moisture absorber for several days, keeping the absorber from directly touching the ball. Avoid oven, clothes dryer, direct harsh sun, and high heat from a hair dryer because those can damage glue, panels, bladder, and shape. If after 5–7 days it is still heavy, lumpy, unbalanced, or "dead" when bouncing, the inner layers are likely waterlogged or damaged. At that point I’d retire it or use it only for light practice, because a heavy volleyball can hurt fingers, wrists, and shoulders.

Final Summary

The AI Roundtable initially split on whether to use passive airflow or desiccant bags, but everything changed when Claude Opus 4.8 suggested deflating the ball to physically squeeze water out of the valve. Recognizing that desiccants alone can't escape a sealed rubber bladder, GLM-5.2, MiniMax M3, Gemini 3.1 Pro Preview, and Qwen3.7-Max all pivoted to adopt this mechanical draining step first. The group universally warned against using direct heat, with GPT-5.5 pro delivering a pragmatic reality check: if the ball doesn't return to its standard 260–280g weight after a week of drying, discard it to avoid wrist injuries.
