6 Ways to Destroy Easter Peeps With Candy Experiments

What's more fun than eating Peeps? Destroying them with candy experiments!

Here are some favorite Peeps experiments from around the internet.

1. Peeps Duel

Have your Peeps duel each other. Stick a toothpick in each Peeps marshmallow and put two in the microwave facing each other. The first Peep to touch the other with a toothpick wins the duel.



2. Testing Stale Peeps

What can you do with old Peeps? Well, they won’t win any jousting contests.

When you microwave marshmallow Peeps, the water trapped inside turns to steam while the gelatin softens, causing the marshmallow to expand. But if the Peeps dry out and go stale, there’s less water to help them expand. That’s why stale Peeps don’t get nearly as big in the microwave--and why they won’t win the jousts.

Check out this Smithsonian video to learn more.


3. Smashing Peeps with Dry Ice

Want to smash Peeps with a hammer? Put them in a cooler with some dry ice. The dry ice freezes the water and gelatin, making your Easter candy as brittle as ice.



4. Giant Peeps, Shrinking Peeps

When you put marshmallows inside a sealed container and vacuum out the air, they grow! Let the air out again, and they collapse.



5. Sink a Peeps

Peeps float because they're less dense than water--all those air bubbles spread the sugar out. But if you smash the Peeps to destroy the air bubbles and make it smaller, you can teach it to swim!



6. Bleach the Peeps

Peeps are covered with colored sugar, which dissolves in water. But because the Peeps marshmallow contains gelatin, the marshmallow part doesn’t dissolve. Place the Peeps in water to create stripes!



Ultimate Destruction!

To see how the scientists destroy Peeps, watch these videos from the Great Lakes Science Center. See Peeps dissolve in sulferic acid, vaporize in molten chlorate, and get electrocuted!

Sinking Peeps and Marshmallows

This Peeps candy experiment sends marshmallows diving to the bottom of a bowl!
What you need:
  • Peeps marshmallow candies
  • Container of water
  • Cutting board and cornstarch (optional)

What to do:
  1. Smash the Peeps marshmallow by rolling it between your palms or flattening it against a hard surface.
    (Hint: sprinkle a cutting board with cornstarch and roll the Peeps in cornstarch to keep it from becoming too sticky as you smash it. You may want to flatten it with a rolling pin.)
  2. Roll the marshmallow into a ball to make it less buoyant.
  3. Drop the smashed Peeps in water.
  4. Does the candy sink?

What's happening:

To sink a Peeps marshmallow, you must make it denser by making it smaller. If you smash it to remove air bubbles and make the marshmallow more compact, you can make it denser than the water. Then it will sink.

Play a game with your friends to see who is strong enough to sink a marshmallow. Anyone who manages to sink a marshmallow becomes a marshmallow champion!

Growing and Shrinking Marshmallows

Make marshmallows shrink and grow in vacuum chamber! You should be able to do this with a kitchen vacuum pack gadget such as a Seal-a-Meal.

What you need:
  • Vacuum seal container, such as a Seal-a-Meal
  • Marshmallows or Peeps candy

What to do:
  1. Place the marshmallows or Peeps in the sealed container.
  2. Attach the vacuum.
  3. Start the vacuum and watch your marshmallows expand.
  4. Turn off the vacuum. Do the marshmallows collapse?

What's happening:
Marshmallows contain tiny air bubbles. The air inside the marshmallows pushes out, while the air around the marshmallows pushes in. When air is pumped out of the container, reducing the air pressure, the air bubbles inside the marshmallow push outwards and cause the marshmallow to grow.

As the marshmallow grows, the air bubbles inside start to rupture. When you turn off the vacuum and allow air back in, the marshmallow shrinks back to normal size. But since some of the air bubbles have been destroyed, it wrinkles and collapses even further.

Sugar and Marketing

Since I'm so interested in candy's science and history, I both enjoyed and was horrified by the book Sugar: The World Corrupted by James Walvin.

I learned that the European desire for sugar fueled the creation of plantations and slavery in the Americas. After slavery 'officially' ended in America after the Civil War, the sugar industry continued to use workers in conditions resembling slavery. These included indentured Indian laborers in British colonies; indentured Chinese and Japanese workers in the Carribean and South America, and poorly paid migrant workers in Florida.

Now our dependence on sugar has caused obesity rates to skyrocket. We're the targets and victims of marketing campaigns whose scope we can hardly imagine.

Amount of money spent on advertising to the young:
  • $792 million on breakfast cereals
  • $549 million on soft drinks
  • $330 million on snacks

"Only the automobile industry spent more money on advertising than the US food industry--understandably, perhaps, when we realise that 12.5 percent of all American consumer spending goes on food."

11 Fun Valentine Science Experiments

Looking for a kid-friendly way to enjoy Valentine’s Day? Try some Valentine science activities at home!

Here’s a roundup of eleven fun Valentine experiments to do with your kids.
  1. Hearts Bobbing

    At www.candyexperiments.com, I love playing with candy. That’s why it was so fun to come up with a conversation hearts experiment that makes the candy dance!

  2. Foaming Elephant Toothpaste

    Add some pink or red food coloring to make Steve Spangler's foaming experiment a Valentine favorite! Not only do kids get to play with foamy bubbles, it’s an exothermic reaction that teaches chemistry.

  3. Foaming Marshmallow Hearts

    Here’s another way to make Valentine foam: microwave marshmallow hearts in a bottle. In just a short time, the melted marshmallow will start fountaining out of the bottle. (Caution--hot!)

  4. Valentine Slime

    Need a Valentine experiment that keeps your kids busy for a few minutes? This Little Bins For Little Hands activity shows how to make some fun Valentine slime.

  5. Catapult for Conversation Hearts


    Here’s a way to try physics in action from the Frogs Snails and Puppy Dog Tails blog. Build a catapult to launch hearts across the room!

  6. Invisible Valentine Messages

    Find instructions at Red Ted Art for writing Valentine messages with invisible ink!

  7. Make Your Own Stethoscope

    Here’s a creative way from Science-sparks to make your own stethoscope and listen for heartbeats as you teach your kids what a heart really does.

  8. Raining Hearts

    Watch hearts sink through different solutions in this experiment about viscosity in action from Inspiration Laboratories.

  9. Test Sour Candy

    Dissolve your candy and add baking soda to see which ones contain acid.

  10. Find the Sour Ingredients

    This mom at Inspiration Laboratories let her kid test each ingredient that makes up conversation hearts to find out which one causes the baking soda to react.
  11. Pierced Hearts


    Poke a pin right through a conversation heart--without breaking it!

A Fountain of Valentine Hearts

With marshmallows, bottle, and a microwave, you can create a Valentine's day fountain!



What you need:
  • marshmallow hearts, such as Peeps
  • empty plastic water bottle
  • parchment paper (optional)
What to do:
  1. Slide the marshmallows into the bottle. (You may want to roll each marshmallow up in parchment paper to slide it inside the bottle, then pull the parchment paper away.
  2. Microwave the bottle, watching closely to make sure it doesn't get too hot.
  3. Watch the marshmallow come fountaining out of the bottle!

What's happening:
As the marshmallows heat up, the gelatin softens while the air bubbles expand, making the marshmallows grow bigger. Since the marshmallows are trapped in a bottle with a narrow opening, the expanding marshmallow gets forced through the narrow bottle top, creating the fountain effect. <
Good news for chocolate lovers! An analysis of several studies, published in the European Journal of Preventive Cardiology, found association between chocolate consumption and a lower risk of coronary artery disease.



The study pointed to consumption at least once a week, but didn't say what kind. Previous studies show the best benefit comes from eating chocolate that's more than 70% dark. Of course, the sugars and fats in chocolate, especially products like cookies, can lead to worse health, so don't go overboard if you make chocolate your new health food!
