How to make a cannon shooting with a pipette
This explosive experiment demonstrates the oxidizing properties of manganese(VII) oxide.
Reagents and equipment:
- potassium permanganate;
- concentrated sulfuric acid;
- test tube;
- plastic pipette;
- cotton wool;
In the interaction of potassium permanganate and sulfuric acid, green manganese(VII) oxide, a strong oxidizer, forms. Its interaction with flammable substances, for example acetone, causes them to ignite.
Wear protective gloves and glasses when conducting this experiment, and follow safety rules for working with flammable substances.
Warning! Don’t try to repeat this experiment without a professional supervision!
