In order to make chemistry lessons more interesting,

chemistry videos are being developed by scientists and lecturers from Chemicum of University of Tartu, Estonia

" is designed for chemistry teachers for showing commented experiment videos in front of classroom.

school programme, some interesting chemistry phenomena is explained:

was filmed with the help of a bomb group. What is cold light or

change color upon heating. Very odd reaction - "

explodes and puts formula model car on the move. Why

. What is the working principle of

and how to prepare these yourself? What makes fireworks colorful (

can be used for igniting safely some pyrotechnic mixtures, for example

Combustion of coal in melted potassium nitrate

Combustion of sulphur in melted potassium nitrate

Combustion of coal in air and oxygen
