Anyone who's ever turned up to science class has probably had an experiment or two go wrong.
Maybe you were exploding gummy bears and the explosion went a bit further than you expected.
Or the laws of physics didn't seem to quite play ball.
Or you dropped something you shouldn't have into a vat of liquid nitrogen.
Let us learn from your past mistakes. Tell us your biggest science class fail and your submission could be featured in a future BuzzFeed Community post!
