Gallium Liquid Metal 50 Grams, 99.99% Pure Melting Gallium - 50g Vial, Syringe, Silicone Mold Cubes, and Complete DIY Science Experiment Guide

Great science experience. Easy to mold and remodeling. However there is a little grey residue that gets over everything. It can be cleaned up by soap and water but it gets everywhere.

Great fun for my 11 year old son!

Satisfied child was able to play with a liquid metal like the boomers did with mercury before they realized that wasnt a great idea :( Advice, outside and clothing you dont care about. It does wash fairly easily off some things, others not. Throw child and clothing in bath/washing machine (respectively) when done and consider double zip-lock bags for storage. Older responsible kids 14+ should be able to handle it on their own. Remember, its not a toy, its elemental gallium, respect it as such and youll have a great time.

Everything I have seen online makes it look like it melts in your hand like chocolate on a hot day. In reality it took quite a while to melt, at least for me. I guess that makes sense. Ice takes a while to melt and your hand is 50f or so above the melting point. For this it is only a few degrees at best. In hot water it melts fairly quickly but takes a while to solidify. Still cool.

Just as I thought-makes a mess. My child begged for this for months. I waited until Christmas, and against my better judgement, I got it. I knew it would not be as great as he hoped. It has to be heated to become fluid. However, it dries very fast and becomes a hard or crumbly mess. Hard to get off surfaces. Left a gray smear like pencil lead all around the kitchen. It will wipe away with a little scrubbing.

Kind of messy but a wonderful birthday gift for my grandson

nice

The worst product on Amazon, period. Parents please be aware. It will make the biggest mess you can ever imagine. It will take you days to get it cleaned up. Definitely not for kids.

Bought this as a gift for my son because he asked for it. He has had lots of fun with it.

Grandson really likes it
