I still remember how much I hated getting cuts and scrapes as a kid...because they meant my mom would douse the spots with hydrogen peroxide and that arguably hurt more!

But it also always did the trick. Since hydrogen peroxide does expire -- you should get rid of it six months after opening -- it can be tough to use the entire bottle up on just bumps and cuts. Then again, if you know all of these awesome uses for the fizzy liquid, you'll find yourself going through bottle after bottle. This stuff is so useful!

First, for easy application, consider getting a spray bottle top for your hydrogen peroxide.

1. Give your dishwasher detergent a boost by adding a splash of hydrogen peroxide to it.

2. Make elephant toothpaste with your kids.

3. Got gunk in your ears? Clean them out with a drop or two of hydrogen peroxide.

4. Get rid of dry, cracked heels by soaking your feet in a hydrogen peroxide and hot water bath for 30 minutes.

Dry them off and scrub with a pumice stone to easily remove the dead skin.

10. Don't just rinse your fruits and veggies -- make sure you're really cleaning them by spraying with some hydrogen peroxide.

11. Keep leftover salad from spoiling and wilting by spraying it with a half cup of water and a tablespoon of hydrogen peroxide.

12. Run some hydrogen peroxide over your toothbrush to clean it.

13. You can also make toothpaste from hydrogen peroxide and baking soda.

14. Pour a half cup of hydrogen peroxide into your toilet bowl, let it sit for 20 minutes, and scrub it clean.

15. Spray down your shower after every use with some hydrogen peroxide. It'll disinfect and keep your grout white.

16. Get rid of acne and acne scars with hydrogen peroxide.

17. Spray pennies or other copper pieces with hydrogen peroxide, vinegar, and salt to give them an antique look.

Well there you have it -- stop just using it on your cuts and start using it all around your home!
In a cool science video, see exactly what happens when blood comes into contact with more concentrated hydrogen peroxide!

We've all used hydrogen peroxide on a cut or scrape at some point in our lives. That burning sensation paired with the foam it creates when it hits the blood is reassurance that our cut won't get infected by anything nasty. But why does it do that?
Well, you've got to understand one thing first...
Most over-the-counter hydrogen peroxides are a solution of the chemical and water. Typically, they don't contain more than three percent hydrogen peroxide. Why so little, you ask? Well, I'll let the video below do the talking...

This is what happens when blood comes into contact with 30% hydrogen peroxide.

What you're seeing is the chemical reaction between the enzyme catalase (which is found in our blood cells) and the hydrogen peroxide itself. When they come into contract with each other, the hydrogen peroxide turns into oxygen and water.
The bubbles you see are pure oxygen being released as a result of the combination. The reaction is also extremely efficient at burning up (so to speak) any bacteria that may have made its way into your cut. Now just imagine pouring that 30% solution on it...yeah, that would have some devastating consequences.
