Mostly everybody knows someone that uses mouthwash. May it be a brother, sister, parent, or friend you'll most likely know someone. And everybody likes pranks (usually). So what could be better than a prank involving mouthwash? In this Instructable I will be showing you how to make a simple, easy, and fun prank.

Step 1: Supplies

You'll only need a few household items, which are:

1: Peppermint Extract
2: Table Salt
3: Lemon Juice
4: Blue Food Coloring
5: Someone's Bottle of Blue Mouthwash
6: Vinegar
7: Hot Pepper Flakes
8: A Tablespoon
9: Garlic Powder
10. Black Pepper

Step 2: Step 1: Vinegar

The first thing your going to do is add the vinegar.
Take a teaspoon and measure out *two tablespoons* of vinegar then mix well.

* You might want to add more or less depending on the size of your bottle*

Step 3: Step 2: Dry Ingredients

The next thing your going to do is add the dry ingredients.

First add about four shakes of both salt and pepper.
Then add three teaspoons of garlic powder.
Next add three teaspoons of hot pepper flakes.
Lastly, mix well.

You might want to add more or less depending on the size of your bottle.

Step 4: Step 3: Lemon Juice

The next part to do is add the lemon juice.

There really is no set measurement, but put about three tablespoons.
Add more or less if you want.

Step 5: Step 4: the Cover Up

What your going to do is add the cover up ingredients.

First add enough blue food coloring to make it return to its natural color.
Then put in just enough peppermint extract to make it smell minty, without any trace of other smells!!
Make sure that all granules or flakes are dissolved.

Step 6: Other Ideas

You could also add in any other ingredients that you think will make it grosser.

Also if your bathroom has a shower and you do this to a family member.
Hide in the shower and film them, its really funny to watch over and over again. (especially in slow-motion)
