Omg don't get this
Omg don't get this. None of the slimes worked for us and it made my kid cry since it was part of his birthday present. He loves science and this was total BS. Just powder and water with the wrong ratios that made nothing. Very disappointing

Don't buy this!
The slimes don't work. They stay liquid and never activate. Made my 7 year old cry.

Slime fail
It never activated as slime. It stayed water. Don’t buy this. Plus you don’t get the three figures - they make you cut them out of the side of the box.
