15 Science Experiments To Try This Easter Break

Endless fun with things you probably have in your kitchen cupboard already.

1. The leak proof plastic bag.

What you need: Sharpened pencils, plastic food bags, water, paper towels (in case of spills), a sink to empty the water out afterwards.

Just fill a bag with water, pierce with pencils, and be amazed. The sharper the pencils, the lower the chance of any leaks. There's no trickery here – just science.

2. The best baking soda and vinegar reaction.

What you need: Bicarbonate of soda, vinegar, a container, a drop of washing up liquid, food colouring (optional).

The secret is to add a little washing up liquid to the vinegar before you mix them together. If you want to re-create this rainbow effect just add different food colourings too!

3. Washing up liquid silly putty.

What you need: Washing up liquid, corn starch.

For a twist on the standard kitchen science experiment of adding water to cornstarch, add some dish soap instead. You can experiment by tweaking the ratio of soap to corn starch to get the texture you want.

7. Lemon volcanoes.

What you need: Lemons, baking soda, liquid watercolours (optional, but pretty).

Lemon volcanoes are a nice (and better smelling!) alternative to vinegar-based baking soda volcanoes. Adding watercolours to the lemon before you add the baking soda makes this a pretty spectacular eruption.

8. Baking soda and vinegar balloons.

What you need: Baking soda, vinegar, an empty bottle, balloons.

Here's a way to mix baking soda and vinegar that WON'T cause a volcano to erupt all over your kitchen worktop. The balloons will end up full of carbon dioxide, which is heavier than air, so these definitely won't float.

11. The quickest way to empty a bottle..

What you need: Empty two-litre bottle, water, sink.

Challenge someone to empty a bottle of water as fast as they can, then show them this trick. You just swirl the bottle to create a vortex, letting air in and water out much more smoothly than just tipping a bottle upside down.

15. Salt pendulum.

What you need: Salt, a funnel, string, drawing pins, black paper or card (or a table cloth you don't mind getting salty), somewhere to hand the funnel.

This requires a little more setup than some other kitchen science experiments, but the effect is worth it.
