18 Science Class Fails That Will Make You Laugh And Then Despair
“Our teacher demonstrated what not to do with a chip pan fire. I’m fairly sure he lost his eyebrows.”

"Our teacher had shown us that the tiniest slice of potassium can fizz around water when she was called out of the classroom. The class clown decided to recreate this cool little experiment. Wanting a larger reaction, he took a chunk the size of a baked bean and threw it into the water. It exploded, shattering the huge glass bowl it was in, sending water and glass everywhere. The entire class sat in silence for a second, then the smoke alarm went off and the entire school had to evacuate to the field."

"In one biology lesson we dissected sheep lungs. The teacher had the idea of ‘borrowing’ the physics teacher's bike pump and using it to pump the lungs up to show how they would inflate in a live animal. Of course, he ended up overpumping and the lung EXPLODED with the whole class (who were crowded round the table) showered with bits of dead sheep and blood."
