Review on 500PCS Sensory Rainbow Wedding Decoration by Sara Gowan

They seemed like a fun pastime - polymer balls are great fun to play with and can really relax you. Unfortunately I didn't get that far with them. Mine had been soaking for about 10 hours and I checked them regularly. It eventually got about the same size as the photo here when I squeezed it slightly - and the polymer ball completely dissolved in my hands and fell into the sink. I had to make an effort to clean all the parts (because such things are not suitable for pipes at all). If I let it set for a shorter time it would be a little more durable, but with the caveat that it's not a full bullet. I can use them for a science experiment, at least for my younger siblings, but they won't be nearly as fun simply because they're structurally unhealthy. Especially considering the environmental hazard of just falling apart everywhere, it's definitely not worth it in my opinion.
