Revisited Experiments

Sometimes a previous experiment is revisited later. Here is a list of all revisited experiments in Is It A Good Idea To Microwave This?.

Revisited experiments

 * #9. Toothpaste.
 * Revisited at #285. This became one of the favorite experiments of the guys ever.
 * #27. Bag of Chips.
 * Revisited at #281. A bigger bag has been used.
 * #32. Glow Sticks.
 * Revisited at #241. In this video Jon explained he always really enjoyed the season 2 glow stick experiment, but he wasn't really happy with the way it was filmed. So in season 8 it was revisited in HD.
 * #54. Lava Lamp.
 * Revisited at #256. For this experiment the top was reinforced to get a bigger explosion.
 * #58 - Ping Pong Balls.
 * Revisited at #103. A jack-o'-lantern with two ping pong balls as eyes was microwaved, but it was kind of a dud. The two ping pong balls were microwaved without the pumpkin.
 * #60. Highlighters.
 * Revisited at #289. This time combined with a book.
 * #133. Spray Paint.
 * Revisited at #213. In the original experiment the spray paint was only about half filled, so in the Season Seven Finale this experiment was redone with a full can.
 * #167. Airbag.
 * Revisited at #274. This time under safer conditions. The used microwave Beth had a time dial and she would start working when she was plugged in from a distance.
