What is stored in this ampoule 🧪 ?? 🤔

An ideal mixture of Dry Ice + hot water is about 1 cup Dry Ice
for every 4 litres of hot water.

Two drops of potassium permanganate are added to give purple color 💜

Explanation: Dry ice is frozen carbon dioxide and turns directly back into a gas as it heats up. When you submerge dry ice in water, it heats up quickly and produces a thick smoke

This will make lots of fog depending upon the temperature of the water
and the size of the pieces of Dry Ice.
Hotter water will make more fog.
Smaller pieces of Dry Ice with more surface area
produce a greater volume of fog
and cool the water down much faster.
