How to Build a Small Pepper Spray Gun
- 1). Put on rubber gloves if you've opted to use them for safety. Pour the 2 tbsp of ground hot red-pepper powder into the small glass.
- 2). Pour all of the rubbing alcohol over the red-pepper powder. Use the mortar, or spoon, to stir and grind the solution for at least 10 minutes. If using a spoon, you will want to ensure that the red-pepper powder is completely dissolved before ceasing to stir. A spoon will not grind the powder as good as a mortar will. A blender may also be used to do this, but you may lose some of the solution by using a blender.
- 3). Add all of the baby oil to the mixture after you've finished mixing for 10 minutes. Stir this new mixture for at least two minutes.
- 4). Place your cloth (coffee filter/paper towel) on top of the second glass. Press the middle of the filter down into the cup a little bit to prevent spilling. Slowly pour the mixture into the filter and allow it to filter down into the glass. This may take a few minutes as the mixture may not filter quickly.
- 5). Take the top off of the small spray bottle. After the mixture has completely filtered into the second glass, pour it into the spray bottle. Close the spray bottle and wipe it down with a paper towel. Spray the mixture into the sink to ensure the tube of the sprayer fills with the spray. Remove gloves.
