2020-8-5 · The answer about platinum was close, but thermodynamically impossible in terms of an ongoing reaction. Instead, they need to perform two transmutations: convert the coins into platinum (doesn''t need to be particularly pure, it''ll work as well in the form of nearly any alloy with iridium, rhodium, palladium, even nickel), ideally in the form of a mesh of fine wire -- then transform the water

How to Create a small explosion with calcium carbide

In order to create an explosion, using Calcium Carbide, you''ll need the following: calcium carbide, water, a dropper, and a lighter. Place a small chunk of calcium carbide in a petri dish. Fill the dropper with water. Light the lighter and hold it close to the calcium carbide, while you drop a drop of water onto the calcium carbide. Pull the dropper back immediately.
