Smooth-On Flex Foam-It! 3 Pourable Flexible Foam Trial Unit by Smooth-On, Inc.

Came fast, works great and exactly as described.

I poured this into a silicone cupcake mold and it quickly puffed up and set into a very pleasing squishy. The only problem I had was that it foamed up a lot, and fast, and I had some bubbles in my squishy at the bottom of the mold, which was of course, the top of my squishy. So next time I am going to try Flex Foam It! 6 or so for the slightly denser foam, and hopefully I won't have the bubbles...

This is a great product. Slightly scary instructions but we found that there were minimal fumes etc. We've made a number of squishies using this. The only trouble is finding suitable moulds to make them from.

We have made foam toys with this kit and its fantastic. Does exactly as promised. 2 polymers combining in a chemical reaction to make a squishy toy.Be careful and adhere to the safety instructions.

This is not for the faint of heart. It is toxic and very very unforgiving. Please watch YouTube videos and read their site for help.It’s insanely sticky, so use silicon forms where you’re pouring.Measure!!! Use a scale, it makes it so much easier. 1A:2B or .575 difference. 10 grams A = 17.3g B. This is insanely important. Very unforgiving. Yellow bottle is the hardener…. Too much yellow it’s too hard or doesn’t expand. Too much blue bottle it doesn’t stay expanded and looks weird.Mix until 35 seconds and your shoulder is on fire. When you combine the chemicals after measuring exactly, mix immediately and use a timer. Mix until your shoulder burns. Really really really mix. Minimum 35 seconds, then pour.Lastly, it doesn’t like cold. Has to be 72+ or it doesn’t fully expand. This is all listed on the website and 100% accurate.Measure - mix - warm - remove after 25 min.It’s a great product and has a lot of uses if you can do the above.
