We put an egg into a container of vinegar and left it for a couple of days. We noticed that the egg sent gas bubbles up into the vinegar. On Wednesday we looked at the egg. It looked golden and gross! It smelt gross and we got to touch it. But... most of the class didn't get to touch it beacause it EXPLODED! Someone popped it by accident. IT WAS SAD. But the skin inside went thick and went tiny and it was see through - but it also did go gross. It smellt terrible.
