Greater than one weekHaven’t weighed it yet to see if it’s 50grams but the tube it came in has cracks in it so it probably won’t last very long but other than that I like it though I wish the long term storage was better

> 3 dayDoesnt melt in your hands, it actually solidifies. Doesnt make pure aluminum brittle (3 hour 30 min test). But its still cool.

> 3 dayI do not recommend this for kids at all. It stained my kids hands. It stained my floor and dining room table. Poor quality.

> 3 dayI read melt in your hands, like 77-79 degrees or whatever, that does not happen, youre going to look like an idiot for hours on end holding this crap in your hand BUT this element is pretty dang cool! I put it in hot tap water (about 115 degrees) and came back and it was melted. Boiling water, no time at all, separates itself from the water, pour it out (carefully, dont wanna accidentally send it down the drain its too expensive) and when it sets up again its surprisingly strong, Id relate to aluminum or maybe stronger when cooled. Its just fun to play with and I used to play with mercury, no problems, but I showed a friend and he freaked out! Watch some vids on YouTube, itll give you ideas

> 3 dayPurchased so i could teach my nephew about interesting minerals. He was extremely excited and the product melted in your hand as it said. The product does take awhile to melt so dont think its instantaneous. Excellent product

> 3 dayJust 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.

> 3 dayIt was fun to play with. Took me forever to figure out how to melt it. Also leaves black stuff on hands but thats normal and comes off super easy
