10 Science experiments you can do with a plastic bottle

Modified: Sep 19, 2024 · Published: Aug 17, 2022 by Emma Vanstone · This post may contain affiliate links · Leave a Comment

These science experiments you can do with a bottle are great for home or school, can be used over and over again and even recycled afterwards!

Make rockets, lava lamps and even a drinks dispenser that actually works! Have a rocket race, find out who can make the longest bubbly snake and discover how much rainfall you have where you live.

Raid your recycle bin and start creating!

Science experiments using a plastic bottle

1. Squeezy Bottle Rocket

Squeezy bottle rockets are a brilliant introduction to forces, particularly Newton’s Third Law of motion. Squeeze the bottle and watch the rocket fly.

2. Make A Model Lung

This model of a lung uses the top section of a plastic bottle to demonstrate how lungs work.

3. Collapse a bottle

Find out how to collapse a bottle using air pressure. All you need for this activity is an empty plastic bottle and hot water!

4. Easy Bubble Snake

Bubble snakes are great fun and only need a plastic bottle, elastic band, small piece of material and bubble mix! Simply blow down the bottle to create a long bubble snake!

5. Baking Soda Rocket

This mini baking soda rocket is powered by baking soda and vinegar. It’s not quite as explosive as the water powered version, but it is a great space themed science experiment and a fun way to learn about forces.

6. Water Powered Bottle Rocket

Use a large bottle to make a water powered bottle rocket. This is a brilliant outdoor science and engineering activity.

7. DIY Drinks Dispenser

This easy DIY drinks dispenser is super simple and great for learning about air pressure with a practical use as well!

8. Fizzy Lava Lamp

I’ve always used glass or plastic jars to make a lava lamp, but they work just as well in a bottle! All you need is oil, water, food colouring and an effervescent tablet.

9. Easy Rain Gauge

Did you know you can make a rain gauge from a plastic bottle? Just cut off the top and place it inside the remainder of the bottle upside down! Record the rainfall each day and find the average at the end of every month.
