Drop a Warhead in baking soda water, and bubbles erupt. Leave a Skittle in water, and the S floats to the surface. Melt a Starburst, and shiny oil spots form. You're doing candy experiments--science experiments with candy.

Melt Halloween candy. Dissolve Valentine hearts. Float Easter Peeps. Or let your kids create their own candy science experiments.

Candy experiments. All candy. All science. All fun.

Ways to project the Eclipse

No eclipse glasses? There are other ways to watch the eclipse in action.

Poke a small hole in a piece of paper (or chocolate bar) and shine the light onto the ground or a screen.





Mount a spotting scope and turn it backwards.



Turn your binoculars upside down and shine the image on the ground.





Make a small hole between thumb and fingers, and use that to project the ecplipse.

Unstick the Marshmallows

Getting test tubes ready for a Candy Experiment author visit, I realized that they all had marshmallows stuck to the bottom. How to get them out?


You can scrape them out, but they just stick back on.


So you float them out.

Bumpy Easter Eggs with Jordan Almonds

How did putting a purple Jordan almond in water turn it into a bumpy Easter egg?

Perhaps the bumpy spots resulted from bubbles sticking to the candy shell, preventing water from reaching and dissolving those particular spots.

A tub of soup (left) after the ski vacation. It was resealed at high altitude, with low air pressure, so that when it reached sea level again, the sides contracted inwards.

Try this yourself by opening and then sealing a bottle in a hot car, or sealing a marshmallow in a bottle at high altitude

Teapot Swirls

Here's something to notice when you're making tea on a cold day. If you pour cold and hot water together, you might notice swirls of light in the water. Not because the water is colored (it's not), but because the hot and cold water have different densities, and thus bend light in slightly different ways. Mix them, and you can see the fluid swirling as light bends at the boundaries between the hot and cold.

St. Patrick's Day Chromatography

Why is the color green such a fun candy color? Because you can separate it with chromatography.

Here’s how to see the dyes that make up the green color on an M&M or jelly bean.
  1. Cut a rectangular strip of coffee filter paper.
    Dab a drop of water onto a plate, then put the candy on the water. This will dissolve a little bit of the color.
    Dab the color to make a spot of color near the bottom of the strip.
  2. Place the strip in a small glass with about a 1/2 inch of water. The bottom of the paper should be in the water, with the spot above the water.
  3. After a few minutes, look for new colors. Can you see any yellow near the bottom? Or blue on top?



And if you have leprechauns and rainbows on the brain, try the experiment with a brown or black piece of candy. You’ll see an array of colors.


Now, that’s a St. Patrick’s day rainbow!
