Review: Making squishys - Works perfect for squishys my daughter used molds and made them it was alot of fun I help her i recommend older help cuz it can get messy
Review: YAY SQUISHIES!!!!!!!! - So my 9 yr old is all about squishies. This product was very very easy to use. However I will warn u. Def wear gloves. And don't let it get on counters, sinks etc. very hard to remove. Also I saw in other reviews to get quick release. I didn't get that and it was very hard to get out of silicone molds. Also when we did it in a plastic container or cup it didn't stick as bad and bottom came out much smoother then silicone molds. The only thing I did have trouble with was the measuring part. Didn't understand the measurements that came with it. So it was a lot of trial and error. Also when we closed containers the B container got stuck like crazy glue stuck. So it's very fun craft to do with ur kids. Just needs better instructions on how to use. I will definitely buy again

## Questions & Answers

**Q: Can i use with plastic? or do i need a release agent?**
A: Urethane foams are adhesive and will stick / bond to many surfaces. We recommend Ease Release™ 2831 to release urethane foam from most surfaces.
If the release application is particularly difficult (example; releasing urethane foam from urethane rubber), we recommend an application of Universal Mold Release™ followed by an application of Ease Release™ 2831. WARNING; Do not use Universal
Mold Release by itself, or any other silicone based release agents. This will collapse the foam.  You MUST perform a small scale test to determine if the release agent you use will work properly with the plastic you are casting against.

**Q: Would this work well for filling a plaster body cast intended to make a dress form for sewing?**
A: I thinking would. It is pretty "squishy " so if that's okay with you then I think it would work well.

**Q: Hi, do you also have smooth on flex foamV or 6?**
A: I am not Amazon and I have not worked with 6 (Pillow soft) but I have a sample of it. The Smooth-On web site says they make sample kits for both products and they are both similar to 3 in that they are measured by volume. The big difference is that they expand less.

**Q: What is the Shore hardness of the resultant foam?**
A: I could not find a Shore Hardness for the Foam (and yes, I know what I was looking for) but since it is their most expansive foam I imagine the number to be quite low. I am not even Shore Hardness applies to foams.

### ⭐⭐⭐⭐⭐ Great for making squishies
*by D***W on December 18, 2018*

Buying squishies and repainting them or buying unpainted ones and painting them yourself is cool, but making your own is even better. I use silicone baking molds, candy molds and ice molds to cast mine and have had great results. This starter package will make a LOT of squishies. It is easy and the company's web site has great videos explaining everything. BE SURE to pick up lots of paint stirring sticks at some place that sells house paint because you will need them. This is great stuff an easy to use. Just know that once you mix the two parts (A & B) together you have have 30 seconds of so to get it in the molds. This is very different from acrylic casting which has a much longer pot life.
