Wally was always a playful one, he never took things seriously until things went wrong. Especially when it came to chemicals, fire and paper. You were actually trying to focus on the test, while he had a big test tube full of ripped up paper that use to be his maths test, almost filling the test tube completely with paper, he had tipped some random chemicals that probably shouldn't be mixed into the tube, and lit up a match. He knew you weren't paying attention, so he made the great idea to carefully lower the match to the paper and watch it burn, he was hoping for a simple explosion.

Barley a few minutes later.

You and Wally stood side by side in the crowed hallway, all the students ran out the room after the explosion, leaving the science teacher to put it out. He rubbed the back of his neck awkwardly, he could feel your eyes burning holes into him.

"I uh.. didn't know the explosion was going to be that big." He murmured awkwardly.
