The Gummies

After you've made your yummy gummy shapes, you can wrap them in a plastic bag and label it with fun rainbow and unicorn stickers that are included in the kit! Your scientific creation is a great sweet and sour treat for your friends and family! The kit comes with enough ingredients to make one batch of each of the following: vanilla white clouds, one- or two-color unicorns, three-color rainbows, and six-color rainbows.

The Experiments

Aside from an experiment to guide you in making your gummy candies, additional experiments explore different chemistry concepts. Can you remove the color from your gummies? What happens when you melt one of your gummy shapes and then freeze it? The experiments in the kit explore the how's and why's in detail.

The Manual

Kids are introduced to scientific terms and processes in the 'Geek Out!' sections of the manual. Things like phases of matter, color mixing, and how our eyes detect color are described in easy-to-understand language and accompanied by clear illustrations, photographs, and real-life applications to make these concepts more tangible.

    Reviewed in Australia on December 26, 2021
    My 7yo daughter had so much fun making these! I read some reviews that the gummies were grainy. This happens when the water isn’t hot enough. We corrected this by heating in the microwave until it reached a smooth consistency.

    Tastes great bright colours. This kit has a very generous amount of powder for each colour. Will make plenty of batches of gummies. We will be purchasing some larger moulds to use up the power.

    I recommend this gummy making kit
