This fun colour-mixing ice experiment is great for learning about freezing and melting and is fun for kids of all ages. Using fruit juice instead of food colouring and water also means you end up with a lovely smoothie drink!
Another easy icy experiment to try is using salt and ice to cool a drink quickly!
What you need for colour-mixing ice
Different colour fruit juices
Ice cube tray
Tray or plate
Colour mixing ice instructions
Place different coloured fruit juices in an ice cube tray and place in the freezer until frozen.
Once frozen, remove the ice cube trays from the freezer and let them melt until they are no longer sticky.
Tip the juice cubes out of the tray and choose different coloured cubes to mix up.
We discussed what colours we thought we could create when the fruit juice cubes melted together.
How can you make the ice melt faster?
We were a little impatient, so we tried to find a way to make the juice cubes melt faster.
We crushed them up and held the cubes to warm them with our hands, and before long, we had a slushy brown coloured juice drink!
If it had been a sunny day, we could’ve also left the cubes in the sun to melt.
In an ideal world, we’d have melted a yellow and blue drink to make green or a blue and red drink to make purple, but we didn’t have all those colours to hand.
Try to invent a drinks holder that protects your hands from the cold of the drink!
Adding foil to this one didn’t help to protect our hands from the cold!!
Why does water freeze?
Water can be a solid, liquid or gas. In liquid form, the water particles can move around freely, so the water takes the shape of its container. When you cool the water down, the movement of the particles slows down, and they become tightly packed together, which means their shape cannot change easily.
Why is ice sticky?
Ice feels sticky because when you touch it, it immediately freezes the moisture in your skin, making the cube feel sticky.
