Why peeps explode

If you truly want a sticky, gooey mess and the explosion, then do not take them out of the original box and leave on the plastic wrap. Set the time on the microwave for about five minutes. Do not handle the microwaved Peeps with your bare hands until they have cooled, or you could burn your hands. Helpful 22 Not Helpful 5. Helpful 20 Not Helpful 5. Helpful 17 Not Helpful 4.

My kids are always disappointed when we take the puffed up Peep from the microwave only to see it instantly deflate. Once the heating stops, the air molecules slow down and stop pushing against the wall of the bubbles and some bubbles burst letting the air out of the Peep.

This, plus the fact that some of the water in the Peep evaporates during heating lead to the collapse of the Peep. One day after looking at our deflated Peeps, we talked about the changes that took place in the Peeps do to heating. We thought about the air escaping and the water evaporating and wondered if this caused a change in mass, or weight. Well, there is only one way to find out. Design a Peeps science experiment!

Weigh your glass bowl. If your scale has a tare feature, use it now. If not, record the weight of the bowl. Next, add a Peep to the bowl and record the weight of the Peep. If you do not have a tare feature on your scale, you will have to subtract the weight of the bowl from the weight of the bowl and the Peep to find the weight of the Peep alone.

Place the Peep and the bowl in the microwave. Heat for 30 seconds. Immediately after the microwave shuts off, take the bowl and Peep out of the microwave and weigh it. Record the weight of the Peep. Again, subtract the weight of the bowl if you did not use the tare feature. Continue this procedure with new Peeps each time increasing the time by 10 seconds until you have reached 60 seconds. Each time you repeat the experiment, it is called a trial. Now that is a dangerous isle!

My kids have been wanting to try this Microwaved Peep Experiment for a while, so we decided to take it to the next level.

My kids were totally memorized watching our simple Exploding Peep Geysers. Once the peeps were all snug in their new home, we realized that our bottle almost touched the top of the microwave.

It would have been easier to do this step first, but oh well. Cut a few inches off the top of the bottle. You will see why this is a good idea as you scroll down. I asked the kids what they thought was going to happen when we microwaved our little ghosts. They predicted that the Peeps would expand to the top of the container. Surprisingly, our little Peeps did more than just expand. Who knew they would explode right out of the bottle. Place your peep filled bottle in the middle of the microwave.

It will only take about 30 seconds before the explosion is over so be ready. The peeps actually fly out of the bottle. How cool is that!
