Step 1: Materials

You will need

  1. Isopropyl rubbing alcohol

  2. Oil (plain cooking oil)

3. Two small containers

4. One spray bottle

5. Ground Cayenne Pepper (Or grind your own)

6. Coffee filter

Thats all you need! I had these around my house, it was FREE!

Step 2: Pour in Pepper

Open the cap and pour a heaping amount! No exact size, but roughly half a cup.

I just eyeballed it and made a pile.

Step 3: Rubbing Alcohol

Next take your rubbing alcohol and pour it into your plastic container. Add up to about 1 cm above the pile of ground pepper

Step 4: Mix It Up!

Get a plastic spoon and start mixing! Stir it for about 2 minutes to really mix it in.

Now let it soak. I waited only an hour because I got pretty tired of waiting

To really make this extremely strong let it sit overnight or even better, a whole day!

Step 5: Add Oil

Now get your cooking oil and add just a little bit. About 1-2 tablespoons. I severly messed up and added way too much oil. Oh well. It will still work fine.

Step 6: Mix It Up Pt. 2!

Start mixing again! Mix for again about a minute or two.

Step 7: Filter the Mix

Place a coffe filter over the top of a cup

No pour the mix over the filter and wait till all the "Juice" seeps through

You now have very fine/pure pepper spray

Just smelling the mix caused my eyes to water! It works!

Step 8: Put Mix in Bottle

Now get your spray bottle and pour your mix in! You can now spray your pepper spray!

Next Step!

Step 9: Defend Your Self!

You now have fully functioning pepper spray! This stuff really works!

You can use it to deter attackers

Prevent animals from eating your plants

Scare off animals

Although I'm not to blame should something go wrong in those situations
