Got a trashcan full of plastic water bottles? Instead of wasting them, reuse plastic water bottles into something useful and practical. Transforming them takes little effort and few tools. Let’s get to it.

1. Create an I-Spy bottle.

This is perfect for road trips! Fill a bottle with rice, small toys, and beads, and create a checklist (visual or text) for kids. Have kids cross off items as they find them.

TIP: Use super glue to keep the cap tightly screwed if you’re worried your child will dump out all the rice and toys.

 

2. Play glow-in-the-dark bowling with plastic water bottles.

3. Cut off the top to reuse as a water bottle planter.

Cut the plastic bottle top off. You can make it as short or tall as you want for your plants. Add dirt, plants, and voila!

 

4. Show kids how to inflate a balloon with baking soda and vinegar.

Using a funnel, fill an old water bottle a third of the way full with vinegar. Dry the funnel, and use it to pour baking soda into a balloon. Fill the balloon halfway with baking soda.

Cover the top of the bottle with your baking soda balloon, but make sure you don’t let the baking soda spill into the bottle prematurely.

When you and your child are ready, lift the balloon and let the baking soda fall into the vinegar. Since baking soda and vinegar create an acid-base chemical reaction as soon as they’re combined, the balloon will start to inflate, filling up with the carbon dioxide gas created by the reaction in the bottle.

 

5. Blow bubbles with a plastic water bottle.

Clean an empty water bottle, then cut the bottom off, making sure the cut is even. Dip the cut end in bubble solution.

9. Separate the yolk from an egg white.

A water bottle with thicker plastic works perfectly. Crack an egg over a plate, then squeeze the empty water bottle slightly to suck up the yolk.

 

10. Water your plants while you’re on vacation.

Use a small drill bit or nail to poke one to four holes into the cap of a plastic water bottle. If you need to water bigger plants, use a 2-liter bottle, keeping in mind that the more holes you have and the wider the holes, the faster the flow of water. Fill the bottle with water and replace the cap.

Quickly insert the filled bottle into your plant’s soil. You may need to press soil around the bottle to keep it upright. And that’s it! Water will drip slowly out of the bottle’s cap while you’re away.

 

11. Use a plastic water bottle as a mailing tube.

12. Make reaching the faucet easier for toddlers.

Use a knife or scissors to cut off the narrow lid and make the channel for the water. The plastic around the lid is thicker, so it may be a little harder to cut through. Also, depending on your faucet and how curved the spout is, you may have to adjust the extender’s holes or use a different bottle so it stays on.
