15 AMAZING Candy Experiments and Activities

Modified: Feb 13, 2024 · Published: May 24, 2021 by Emma Vanstone · This post may contain affiliate links · 1 Comment

If you asked my son what his favourite all time science experiments are, he’d probably say the bottle rocket, followed by his candy house, so today, we’ve got some great candy experiments and activities for you to try at home.

These easy science experiments with sweets are great for using leftover sweets after Halloween or Christmas or just whenever you fancy doing a special science investigation.

If kitchen science is your thing, please check out my new book Snackable Science, which is available from Amazon now! You can find out how to make marshmallows, lollypops, a chocolate bridge and lots more edible investigations, including lots of candy science experiments.

Easy Candy Experiments for Kids

Candy Towers

These super simple candy towers are great fun, easy to build and taste great, too! We used liquorice allsorts ( not sure if they’re a UK thing ), but any sweets with flat sides work well.

Candy Chromatography

Candy chromatography is a fantastic visual science activity, and you can eat the sweets afterwards (minus a bit of colour ).

Make a DNA model

Create an edible DNA model. Our next challenge is to make a super long version!

Sorting Sweets

Make a mixture of different types of sweets and then sort them by shape/size or colour and create a DUPLO bar chart to show your results.

What makes popping candy pop?

Find out what makes popping candy pop by leaving it in different liquids. Will it pop or not??

Can you dissolve a marshmallow?

Try dissolving marshmallows in this fun activity from Fantastic Fun and Learning.

Design and build your very own candy house!

Build a candy house and test for the best kind of ‘cement’.

Another similar idea is to build a Gingerbread House.

Candy Structures

Towers made from marshmallows and spaghetti are one of those candy science experiments most people have tried and loved. Kids can also use gumdrops and toothpicks to make it slightly different and possibly a bit less sticky.

3D shapes are also fun to create this way.

You could also use a candy tower for an earthquake investigation. Build towers in different edible foundations and shake to find out which foundation is the most stable.

Skittle Science

Add some Skittles to water and watch what happens. The colours should dissolve in the water. You might even see the ‘S’ separate from the sweet! Everyone loves the infamous skittles experiment!

Grow your own rock candy

Did you know you can make your own rock candy by growing sugar crystals? This is a great activity for learning about saturated solutions and crystallisation.

Housing a Forest has some great ideas with Pixi Stix.

Can you blow up a balloon with pop rocks like Steve Spangler?

Do you wish your sweets were bigger? If you put them in water, they will grow, but they might not taste as good.

Sweets which have been expanded with water

We made a filter for toys, but a candy filter would be great fun to design and build.

Try testing your candy for reactions in this fun activity from Inspiration Laboratories.

Practice making predictions with this great sink or float candy experiment from Reading Confetti.
