Burning vacuum cleaner

Today was a public holiday. In the morning I took out some methylated spirits and set some flowers on fire.

And in the afternoon I took an old vacuum cleaner that was getting noisy and put a potassium nitrate and sugar mix into it and set it alight. I never thought it would explode, just expected it to burn out.

vacuum cleaner loaded with potassium nitrate and sugar, plus some fireworks,

And the photos - the last one looks like it has its tongue hanging out :)
