Slime becomes sticky as it melts back into glue when exposed to warmer temperatures/heat through the shipping process, or simply as it breaks down over time. Don't worry - there's an easy fix.

Adding small amounts of activator and kneading it in will turn your slime from sticky to playable again. We cover it all in our Slime Care guide - be careful not to overactivate it!

The activator we use is a very diluted borax-based solution. This is the magic solution that turns glue into slime!

You should activate your slime frequently; whenever it gets too sticky for your liking. This maintains your slime and prevents it from melting back into glue. It's hard to revive completely melted slime.

You would have received a small ziplock of white borax powder to make your own activator (read our Slime Care guide for instructions). Alternatively, you can use contact lens solution as an activator (as it contains borax) or purchase borax from any supermarket.

Leave it in a warm place (a bright windowsill is good) or under the sun and wait for it to melt a little. The heat will melt your overactivated, stiff and rippy slime into a soft, stretchy, playable slime.

If you have some glycerin on hand, you can add a drop at a time and knead it in. This is a quicker and more instant way to reverse overactivation.

Your slime is overactivated! Overactivated slime feels stiff, hard and rips easily when stretched. This can happen if you added too much activator to your slime.

We always overactivate our slimes slightly before shipping them out. Overactivation is needed to combat slimes from melting too much during the warm shipping process (hot delivery vans as posties drive around all day) .

If your slime arrives overactivated, it's because it did not endure as much heat as expected during transit. Put it in a warm place for a little bit and it will melt into a perfect slime. It beats receiving a completely melted slime that is hard to revive.

During winter or when it's cold out, you will notice that your slime feels hard when you first play with it. This is because cold temperature stiffens slime (but extends its lifespan too). Warm it up with your hands and your slime will be the right texture for playing.

During summer or when it's warm, you will notice your slime gets sticky quicker. More frequent activation and care is needed to keep your slime from completely melting. Combat this by keeping your slime in a cool spot.

Clay-based slimes like our Marshmallow (butter) slime, Jelly Putty and any DIY clay toppers mixed into slime will shrink/deflate over time. This occurs naturally when the moisture in the clay evaporates over time or through repeated play. If your slime is kept in an air tight container, it should still be playable for months as shrinkage will not affect its playability.

Floam slimes dehydrate over time as well as styrofoam balls absorb moisture from the slime. You can add small amounts of water and activator to get your slime back to its original volume.

Clear slime gets foggy over time as natural oils and skin cells from your hands transfer onto the slime through play. Always remember to wash and dry your hands before play so you can keep the clarity of your clear slimes for as long as possible.

Yes it will! It turns silvery because of all the tiny air bubbles you are trapping in the slime through play.

Once you return the slime to its container, air bubbles will rise to the top gradually, leaving your slime looking the way it was originally.

With proper care, slime can last you a few months of play, sometimes even more :)
