If you carelessly mixed the two substances used to power the Messerschmitt Me 163 Komet, it was most likely the last thing you ever did. C-Stoff (methanol, hydrazine, and water) added to T-Stoff (hydrogen peroxide) created a violent reaction that propelled the rocket fighter, but could cause a massive explosion if they accidentally mixed.
