Can You Microwave a Squishy? Why You Should Never Heat Squishy Toys

If you've seen viral videos of people putting squishy toys in the microwave, you might be wondering: Can you microwave a squishy?

No. You should never microwave a squishy or intentionally heat a squishy toy. Heating can cause some squishies to melt, expand, split, leak, or burst. Depending on the materials and filling inside, the contents can become extremely hot and may cause serious burns.

The U.S. Consumer Product Safety Commission (CPSC) has specifically warned consumers not to microwave squishy toys after viral social media videos encouraged children and teens to heat them.

Whether you own a soft squishy, gel-filled squishy, slow-rising squishy, crunchy squishy, or another sensory toy, the safest rule is simple:

Keep your squishies away from microwaves, heaters, hot cars, and other high-temperature environments.

What Happens If You Microwave a Squishy?

What happens to a squishy when heated depends on how the toy is made.

Squishy toys come in many different materials and textures. Some are made from foam, rubber, silicone, or other soft polymers, while others may contain gel, beads, water, liquids, powders, sand, or other fillings.

When these materials are exposed to microwave heat, several things can happen.

1. The Squishy Can Become Extremely Hot

The outside of a squishy may not always show how hot the material or filling has become.

Some fillings can retain significant heat. If the toy breaks while being squeezed or handled, hot material can come into contact with the skin.

This creates a serious burn risk.

2. The Squishy Can Expand or Burst

You may have seen videos showing a squishy getting bigger after being placed in a microwave.

That does not mean microwaving a squishy is safe.

Heating may cause air, moisture, gel, or other materials inside the toy to expand. Pressure can build inside the outer skin until the squishy splits or bursts.

If that happens, hot filling can escape suddenly.

3. The Outer Skin Can Melt or Weaken

Many squishy toys are made with soft, flexible materials designed to be squeezed at normal temperatures.

They are not designed for microwave heating.

High temperatures can soften, distort, weaken, or damage the outer layer, making tears and leaks more likely.

Even if the squishy appears normal after heating, its structure may already have been damaged.

4. The Filling Can Leak Out

Some squishies contain gel, water, beads, liquids, powders, sand, or other sensory fillings.

If the outer layer tears after being heated, those materials can leak out.

A damaged or leaking squishy should no longer be used.

Why Are People Microwaving Squishies?

One reason this question has become more common is the popularity of squishy videos on TikTok and other social media platforms.

Some videos show people microwaving squishies to see whether they:

• grow larger

• become softer

• change texture

• inflate

• melt

• burst

These videos may look satisfying or interesting, but they should not be recreated at home.

The CPSC has warned that viral social media content encouraging children and teenagers to microwave squishy toys can lead to serious burn injuries.

A dramatic reaction in a video is not evidence that the experiment is safe.

Can You Heat Up a Squishy Without a Microwave?

It is best not to intentionally heat a squishy at all.

That includes:

• microwaves

• ovens

• boiling water

• hair dryers

• heaters

• heating pads

• hot surfaces

• prolonged direct sunlight

• hot cars

A squishy does not have to be inside a microwave to become dangerously hot.

The CPSC warns that squishy toys can also become dangerously hot when left inside a hot vehicle, near a heater, in prolonged sunlight, or in another high-temperature environment.

For normal use, keep your squishies at a comfortable room temperature and follow any care instructions supplied with the product.

Can You Put a Squishy in Hot Water?

Unless the manufacturer specifically says that a product can be exposed to hot water, you should avoid doing so.

Hot water can potentially affect the outer material, adhesives, coatings, decorations, seams, or filling of a squishy.

If your goal is to clean your squishy, use the care instructions provided for that specific product instead of using heat.

Different squishies can be made from very different materials, so there is no single cleaning method that is appropriate for every type.

Can You Microwave a Squishy to Make It Softer?

No.

A microwave should not be used to change the softness or texture of a squishy.

If a squishy feels harder, firmer, stickier, or different from when you purchased it, heating it is not a safe solution.

Changes in texture may occur because of age, storage conditions, repeated use, material differences, or deterioration.

If a squishy becomes unusually sticky, starts leaking, develops tears, or shows other significant signs of deterioration, stop using it.

Can You Microwave a Slow-Rising Squishy?

You should not microwave a slow-rising squishy.

Slow-rising squishies are designed to compress when squeezed and gradually return toward their original shape.

Heating the toy will not safely improve its slow-rising effect and may permanently damage the foam or other materials.

The satisfying part should come from the squeeze — not from changing the toy with heat.

Can You Microwave Gel or Water-Filled Squishies?

No.

Extra caution is especially important with squishies containing liquids, gels, beads, or other fillings.

Heating the contents may increase the temperature and pressure inside the toy. If the outer layer fails, the heated filling can leak or burst out.

Some fillings may also create additional risks if swallowed or released from a damaged toy.

Never intentionally puncture or open a filled squishy to see what is inside.

How Should You Store Squishies Safely?

Proper storage can help protect the texture and condition of your squishy collection.

For most squishies, a few basic habits are helpful:

• Store them in a cool, dry place.

• Keep them away from direct heat.

• Do not leave them inside a hot car.

• Avoid prolonged direct sunlight.

• Keep them away from sharp objects.

• Inspect them regularly for tears or leaks.

• Follow the manufacturer's care instructions.

• Keep damaged squishies away from young children.

If you collect handmade squishies, remember that different textures and fillings may require slightly different care.

What Should You Do If a Squishy Is Damaged?

Stop using a squishy if you notice significant damage such as:

• tears

• punctures

• leaking filling

• loose pieces

• unusual stickiness

• major discoloration

• deterioration

• strong or unusual odors

Do not microwave, heat, cut, puncture, or otherwise modify the toy in an attempt to repair it.

For children in particular, damaged squishies should be removed from use because exposed filling or loose pieces may create additional hazards.

Are All Squishies the Same?

No — and this is one of the most interesting things about squishies.

"Squishy" describes a broad category of soft, squeezable sensory toys rather than one single material or texture.

Depending on the design, you may encounter:

Slow-Rising Squishies

Soft squishies that gradually return toward their original shape after being squeezed.

Zero Bounce-Back Squishies

Soft, moldable squishies designed to hold their compressed shape longer with little or very slow rebound.

Crackle Squishies

Squishies designed to combine squeezing with a satisfying crackling sensory experience.

Crunchy Squishies

Textured squishies featuring fillings or components that create a noticeable crunchy sensation when squeezed.

Slushy Squishies

Squishies designed around a soft, slushy-style sensory texture.

At QadroNumi, we love exploring these different squishy textures because the experience can feel completely different from one design to another.

No matter which texture you prefer, however, squishies should be enjoyed by squeezing them as intended — never by heating them.

Frequently Asked Questions About Heating Squishies

Can you microwave a squishy?

No. Never microwave or intentionally heat a squishy toy. Heating can cause the toy to become dangerously hot, melt, leak, split, or burst.

What happens if you microwave a squishy?

Depending on its materials, a squishy may expand, soften, deform, melt, leak, or burst. Its filling may also become extremely hot and create a burn hazard.

Can a squishy explode in the microwave?

A heated squishy may expand, rupture, or burst as heat and pressure build inside it. This is one reason squishy toys should never be microwaved.

Can you heat a squishy to make it bigger?

You should not try to make a squishy bigger using heat. Viral videos showing heated squishies expanding should not be recreated.

Can you heat a squishy to make it softer?

No. Microwaving or otherwise heating a squishy is not a safe way to change its texture.

Can you put a squishy in hot water?

Avoid exposing a squishy to hot water unless its manufacturer specifically says that it is safe to do so.

Can you leave squishies in a hot car?

No. High temperatures inside a vehicle can heat a squishy significantly and potentially damage it or create a burn hazard.

Are squishies safe to play with after being microwaved?

If a squishy has been microwaved or significantly overheated, do not continue squeezing or handling it as though nothing happened. Heating may damage the outer material or make the filling dangerously hot.

The Bottom Line: Never Microwave a Squishy

So, can you microwave a squishy?

No. Squishies should never be placed in a microwave or intentionally heated.

The viral videos might look entertaining, but the possible result — a melted, leaking, or bursting squishy filled with extremely hot material — isn't worth the risk.

Instead, enjoy squishies for what makes them so satisfying in the first place: squeezing, pressing, reshaping, collecting, and discovering different textures.

From soft slow-rising textures to crackle, crunchy, slushy, and zero bounce-back designs, there's already plenty to explore without adding heat.

Keep it cool. Keep it squishy. Keep squeezing.
