poor service and poor product

DO NOT STORE IN GLASS. GALLIUM IS MESSY. (Further details in comments)Shipping take about a week, maybe a few days longer. It ships from China, so that’s the speed you’d expect. Faster shipping would cost a LOT. I will not take any starts off for this shipping.100g arrived as two tubes filled with 50g each (I haven’t weighed it but will later) the tubes have lids that are glued shut. Upon opening one lid broke away from the tube (due to cold I believe)It’s exactly what it says, about 100g of gallium metal. This stuff is fun to play with but BEWARE! GALLIUM IS MESSY. It has strong wetting properties and is very soft when liquid. It will turn your hands black and stick to your table. BE CAREFUL.Fun experiments: you can scratch aluminum and place a drop of gallium on top. The gallium will form an alloy with the aluminum that’s weak and the can will slowly crumble!I put some gallium in a solution of copper sulfate and have had metallic copper precipitating from the solution as the gallium replaces the copper.Soap and water is good for removing gallium from your hands, and I’ve found tissues rubbed on tables with a smooth surface can remove the gallium stain.I transferred my gallium into a 2L soda bottle preform. The gallium coated the inside of the container so that you can not see where the gallium is from the outside.Gallium expands as it cools just like water. Because of this, a glass container can shatter if gallium is allowed to cool inside. BE CAREFUL WHAT CONTAINER YOU CHOOSE.

Exactly as advertised, great gift for a 13-year old to try to get them interested in science.
