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.

Candy Flag

Mini M&Ms on a flat surface form a flag as they dissolve.

To repeat at home: arrange mini M&Ms on a small flat rectangular surface with raised edges. (This one is a lid from a plastic resealable container.) Using an eyedropper, gently drip water into the middle of the rectangle and let it spread out. Make sure that you are not squirting the water in one direction or another--if the water is flowing in any direction, it will push the dissolving color that direction. Above all, do not stir!

Because the candies are regularly spaced, the dissolving solutions push against each other as they spread, creating the stripes.

Dancing conversation hearts

The rough surface of a conversation heart provides perfect places for bubbles to form (nucleation sites). When the heart is dropped in club soda, the carbon dioxide dissolved in the water forms bubbles that make the hearts rise. At the surface, some of the bubbles pop or get shaken off, making the hearts sink again.

Try this with Brach's hearts in club soda, or Necco conversation hearts in Sprite.

M&M Decoration Eyes

It's easy to turn M&M's into candy eyeballs.

Place M&M's in a bowl, and pour enough water to submerge 3/4 of the M&M's.
(The tops should still be above water.)

Let the colors start to dissolve.

When the colored shell has dissolved, leaving only white color with a circle on top, remove from the water.

Let the M&M's dry.

Apply to your favorite craft!

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.
