Ice Fire.
This is the acetate type of sodium. It is in liquid form, but even a small impact causes the material to solidify. This material is difficult to cool. It is used to make chemical hot packs.

Self-explosive powder.
Nitrogen triiot looks pretty much like clumps of dirt. However, this is an unstable material. Just a slight impact is enough to cause the substance to explode. They are mainly used in experiments. When they explode, they produce purple-red smoke.

The gas “sinks itself”
. Hexafluoride gas is heavier than air. When “locked” in a sealed container, it automatically sinks to the bottom of the barrel. This colorless gas normally holds objects on its surface. We can “pick” this gas out with a common mug.

Metal melts like ice cream
. This metal is quite similar to mercury, called Gallium. It can melt at room temperature. If an object made of gallium is placed in a cup of hot solution, it will quickly dissolve into this solution.
