Here’s another easy kitchen science activity for kids. Most of the ingredients are what you’d find in your pantry. The only difficult one to get when you’re in lockdown would be the citric acid, but if you bake you might actually have it (it’s an ingredient used to make things sour).
So, what you’ll need for 1 full-sized bath bomb:
- 2 tablespoons citric acid powder
- 4 tablespoons baking soda
- 2 to 3 drops of food colouring
- 1/2 teaspoon of olive oil
- a small plastic toy
- a few drops of essential oil or oil-based perfume of your choice (optional)
- water-soluble sprinkles (optional)
- egg-shaper
- mixing bowl
- spatula
How to do it:
1. Mix together the citric acid and baking soda. If you want to do more just do a 2:1 ratio with 1 part citric acid to 2 parts baking soda.
2. Add in the olive oil and essential oil.
3. Slowly add the food colouring drops
4. Mix everything together so the colour and oils are evenly distributed in the mix.
5. Fill the lower half of your egg shaper with the mixture and hide the toy inside.
6. Fill the top half of your egg shaper. Bring the two halves together. Make sure that both halves are packed tightly so it doesn’t crumble.
7. Let dry for about half a day (putting it under the sun means getting it to dry faster so you can use it in about an hour or two).
Please note that when you use the bath bomb in the tub it will colour the water and might leave colours on your skin. So try to rinse it off your skin and the tub as soon as it fizzles out.
Below is what it would look like when you put it in water.
