7 Top Science Experiments for Kids :)

We love experimenting in our house- from exploding balloons with Citric fruits to erupting home made volcanos, it's all great fun and a brilliant way to keep them entertained during the summer holidays! 

So here they are , our top 7 Science Experiments .

All you need for this experiment is : 

A clean 1 liter clear plastic bottle Vegetable Oil Fizzing tablets (such as Alka Seltzer) Food coloring 

Water ( to fill your bottle, 3/4 full)

Pour the water into the bottle. Slowly pour the vegetable oil into the water bottle, ensuring you give it time to settle . 

Add between 8-10 drops of food coloring to the bottle. The drops will pass through the oil and then mix with the water below. Break a seltzer tablet in half and drop the half tablet into the bottle.
