Fizzy Rainbow Experiment!
STEP 1: Gather your supplies
Before you get started, gather up all the supplies you need for this rainbow science experiment. The kids will be so excited once you get started that you will want to have everything to hand!
- 2-ounce paper cups (or any small containers you can find)
- Baking soda
- Food colouring
STEP 2: Prepare paper cups
Fill each paper cup 3/4 of the way full with baking soda. Be sure to have enough for each colour you want to use!
TIP: Before starting I would advise lining a tray with parchment paper to do this experiement on to minimize the mess!
STEP 3: Add food colouring
Next, add a few drops of food colouring in each cup. you will need to add a different colour to each cup to create a rainbow effect (see image below).
Mix each colour into the baking soda well until the colour has been well distributed as shown below and then line the cups up on your tray covered with parchment paper.
STEP 4: Add vinegar
Now for the fun part! Your baking soda science experiment is now set up and ready to go !
Pour vinegar into each cup and watch the colours erupt. The baking soda and vinegar will react as they come into contact to create a fizzy rainbow eruption!
The kids will be amazed as the watch the baking soda explode and they will want to do this easy science experiment again and again!
We hope you enjoy trying this super fun baking soda science experiment!! Toddlers and preschoolers as well as the big kids are sure to LOVE watching the different colours erupt. Science experiments for kids are so much fun to do, they are a great learning experience for young children and they are in awe watching. This rainbow science experiment is sure to catch their attention!
Here’s a super EASY and fast science experiment to do with the kiddos…magic milk!
All you need to do is fill a dish with about an inch of milk then drop food colors all over randomly. Dip a Q-tip into dawn dish soap then press it on the milk to watch the colors react! The dish soap does not mix with the milk. Instead it floats on top and spreads over the surface. As it spreads, it grabs the food coloring. Soap is a “degreaser” so the molecules in it are attacking the fat in the milk, causing motion which creates the swirling of the colors.
