- Add Color Fizzers and watch the Water Jelly Crystals change color
SKU: 800189 (100 g, 3.5 oz – Clear)
In the color packs, can I pick the colors?
No, the packs are created with color mixing in mind. Our clear crystal packs are limited to being clear. The three and four packs both come with the primary colors – perfect for color mixing! The four pack does include clear as well in case you’d like to try your hand at coloring them yourself.
How long do they take to grow?
They grow in less than a day, so if you throw them in water before your students come to class, they should be ready for your little scientists to play with after lunch.
Is this what they put in flowers?
INDEED!! Using jelly crystals will help to reduce the amount of watering that you will need for your plants during the planting season. For additional information about planting with Jelly Crystals – check out our lab on the matter!
What temperature should the water be at?
Through all of our rigorous testing, we found that they crystals grow better in warmer water than they do in cold.
