Defective product; Read reviews before purchasing

My 6 yr. old nephew purchased this from Walmart store today; PhD mother helped him with this while following all the instructions precisely. Did not work despite repeated attempts; We teased her about this, however she was vindicated when we read all the horrible reviews for this defective product. Unhappy child and frustrated parent. DO NOT purchase this product for yourself or as a gift. You will likely be disappointed. I called the manufacturers toll free number on the box and received voicemail. I am attempting to obtain a refund or I'll just take it back to Walmart.

Could not get this to work

The sodium tettraborate solution did not disolve. Next time we'll just make it from scratch.

Kept them busy

This product did keep my kids busy for a while. INSTRUCTIONS MUST BE FOLLOWED TO THE LETTER. The water must be warm enough to disolve the sodium tetraborate. If it does not disolve it will not work. If the measurements are off it will not work. If you do any thing out of order it will not work. If you do not clean all utensils and measuring cups between batches it will not work. We do like this product, next time we will skip the glitter though. It doesn't stay in the goop. It got all over the kids everytime they play with it.


My daughter made this slime over the weekend and she loved it! It was super easy for her to follow the instructions and the kit came with plenty of glitter to make it extra sparkly. It was great that the kit included everything she needed so she didn't go searching through my cabinets at home looking for ingredients.

Soo bad

It looked like chewed up gum and the food coloring is spilled and also, it tears apart when you try to move it or anything.

The worst!

This is THE worst slime kit that's ever been bought or gifted to my children (and believe me, we've gone through a ton of slime kits.) We have tried the Galaxy slime, Zombie slime, and unicorn slime from Horizon Group USA and they have all been huge disappointments. Save your money & frustrations and just make it from scratch, people. Elmer's glue, baking soda, food coloring, and eye contact solution actually makes what you want, NOT this product. If I could give zero stars I would.

Terrible product

We followed the directions on the box, and it never mixed up, the glue just got all stringy and nasty. Was a Christmas present for my kids and they were so dissapointed. Waste of money and time.

A best buy!

I bought this product with my uncle (one package) for my brother and me (age 10/9), my cousin (age 13/14), and my other cousins (age 12/13). They enjoyed it very much! Only thing is that when we tried it the first time the measurements were a bit off, results: somewhat not flexible. When we tried it the second time we were on point! Therefore we were very pleased with the results! I totally recommend this product!

Big Fun

We made the three color scented Slimygloop on Christmas morning. It worked great. My 4 year old was so happy!!! The key is to spoon the sodium solution as needed to make it think.

Not easy

The instructions seem pretty straight forward, however execution is not easy. Had to throw it away. Next I will buy slime that is already made.
