Making slime easy.
We used this with the AmazonBasics School Glue and some food coloring and got great results. It isn't perfect, but almost as good as the best slime we've bought retail, and the kids love the process. The instructions say add a few drops at a time so we did, but it took a decent amount to get it looking anything like slime. We used a 1/2 cup of glue and ended up having to put at least a couple of good squirts in to get anything to really happen. I thought we had bought a dud, but it really came out great. My son has been playing with it for a few hours and it was perfect the next morning after storing in a ziploc bag. This container will make a TON of slime. I think it will easily outlast the gallon of glue we bought. Great purchase. An actual ratio of activator to glue would have been nice, but not too hard to figure out. I'll try to come up with that ratio or at least a starting point and update this review.

Slime-making — such a fun activity for children - and this activator guarantees success.
It was slime making day today with my grandchildren - a resounding success! Only one tablespoon of activator makes a huge ball of slime, so we have many slime making days ahead of us! They loved it, and I loved that they loved it. A win-win.

Not fool proof.
I bought this for my kid who like making slime but has difficulty with the right formula. I thought this would make it easier but they still couldn't get the slime in the right consistency. It went in the garbage. Perhaps this stuff works but my kid couldn't get it to work so be aware it isn't automatic.

Best birthday present
Our granddaughter evidently loves playing with slime. We asked what she wanted for her birthday, the answer was borax to mix with glue so she could make slime Since she received it, we've gotten several pictures of her playing with her homemade slime.

Not working good
For some reason, the slime is either to liquid or to hard but no good elasticity, I tried a different one and it worked and used it the same amount as this one,
