Alright, so this isn't technically a madbull grenade. But it does function similarly, and is much less expensive. This uses a few household items and is very effective, requires no water balloons, firecrackers, or anything specific other than what is required in the instructions section. I have spent almost a year hunting down an effective airsoft grenade. I felt like I was about done when I saw a youtube video on this. Now, I was skeptical at first, but this is the one of the best grenades. Period. So I improved the design, then since I didn't find anything about this on this site, I decided to post it.
P.s. Sorry for the fuzzy pictures. I need a new camera.
Step 1: Getting your supplies
So you'll obviously need a few things First of all, you most likely will not have the main part in the grenade. The spring loaded party popper. So go down to party city and buy some. I bought 3 for $3.00. No you may be scared at first when the box says " One time use only" but I assure you. These are very easy to reuse. So now that you have those, you will need:
Duck tape ( Or any tape, Duck tape just looks cool.)
A small screw ( One for each grenade. It is very important you get the right size so try a few different types)
An easter egg. ( Preferably with holes in the top, and I think yellow looks coolest)
Sand Paper. ( I find a rotary tool to be much easier, but you may not have one.)
And of course, Air soft pellets. ( I used .2 grams)
There you have it! you can start building now
