How to make Pepper spray at home!

In this instructable, I will be showing you how to make your own Pepper spray at home!

Commercial Pepper spray is made using capsaicin, the active chemical in chillies. We will be extracting capsaicin from chillies using acetone solvent extraction. We will also add a pepper extract for coughing and sneezing effect.

DO NOT WORRY, there is no complicated chemistry involved in this instructable.
I am not responsible for any harm you cause to yourself, or others, in the process of making, or using, these chemical solutions.
Be very careful with this as it causes coughing, sneezing, temporary blindness, and severe pain.
Please note this is illegal in certain countries and should only be used where it is legal. Only for use in self defence.
The effects will only last for 30 seconds, but the pain may last longer.

Step 1: Equipment and ingredients

First, you will need to get a few pieces of equipment and ingredients together.

Equipment:
Coffee filter papers
3 small glasses
A funnel
250ml acetone

Ingredients:
10 chillies (scotch bonnet chillies or hotter. hotter is better!)
About 50g of ground black pepper
Food colouring of your choice (I used red)





Step 2: Preparing chillies

Now, we will prepare the chillies so we can extract the capsaicin from them.

First, chop up the chillies as finely as possible. Put them in one of the glasses. Try to compact them down a bit.
Mash them with a fork until the are in a pulp. Make sure there are no large lumps or the extraction will not work well.

This is good to deter dogs, when you are biking. Some weeks ago one of them bit me.

sometimes you can find a aerosol can where the air can be refilled via base. just put the mix in the top through the used up can. then refill the PSI. (DO NOT EXCEED 100 PSI THOUGH MIGHT EXPLODE)

I saw he price tag on your acetone and was shocked. You can get pure acetone at your drug store or cosmetics supply (mine is a CVS) right with the nail polish remover. I recently paid under $4 for a 300 ml bottle. Hope this helps.

I pay about $3 for a pint of pure acetone @ Wal-Mart.

we did it the old school way back in my highschool days, soak about a pound of dried cayanne in high proof rubbing alcohol, filter, then boil off the alcohol. put it in a nasal spray bottle, you're all set. PS, afrin bottles "mist" so it's more like tear gas.
oolala170 (author)  illuminatis7 months ago
yeah you can use alcohol, or any solvent but you want the least poisonous. also you would want hotter chillies than cayenne peppers. nasal spray is a good idea!

Good idea, although I would combine this with two extra ingredients to make it more effective.

Go to the store and get some penetrating muscle rub, OR teatree oil. Both of these help medication or mixtures to better enter the skin, causing a longer and more intense effect. Plus tea tree oil smells really strong, and is a hard odor to get rid of.

Another ingredient is to go get a high quality highlighter pen and take the ink out of it and mix that in. Most commercially available sprays have dyes like this in it to show up under UV light, so your assailant can be more easily identified later by police.

that is a great idea! I could also put in vicks menthol rub which really stings the eyes
