Bests & Worsts Reviews from Amazon

I am interested in chemistry (I am 15) and I had some extra money. So I thought I'd buy an interesting element and I stumbled across gallium. I bought 40 grams from them melted it down into an ingot with some warm water. And I thought I'd weigh it when i did my scale said it was only 10 grams I contacted the company through amazon to tell them and then forgot about it. 2 weeks later i received the 30 grams of gallium that I didnt receive. The customer service was amazing, But there are some things I have discovered. First this DO NOT let this be messed around with by anyone below 11 years old. It is very messy/sticky. And if spilled it is very hard to clean up (I spilled it within the first 5 mins of melting it. Second (optional) wear latex gloves when you liquefy it just to make sure not to get any on your skin though it is non toxic it is not the best thing to be in your body. Third DO NOT and I mean DO NOT store in a glass container when the gallium hardens it expands if stored in glass it will crack the glass which can cause injury. Also when melting it I put a glass of water in the microwave for 1 min 30 secs and put the container with the gallium in it for about 10 mins (make sure to hold the top closed or the steam from inside will pop the top open) and dump it into a container that you want it to be stored/made into the shape of. Then stick in the freezer for around 30-45 mins. At first i used cheap plastic party cups so that when it hardens you can cut the cup and remove the hardened gallium. (Also you will have to wait a LONG time for it to melt in your hand). Also the picture is the ingot I made of my 40 grams of gallium.
