The video demonstrates how to create a vinegar grenade using two water bottles, baking soda, and vinegar. The process involves rolling up baking soda in paper towels, filling a water bottle with vinegar halfway, inserting the paper towel into the water bottle and sealing it with the cap. The key is to shake it slightly before throwing it to create pressure for the explosion. The video emphasizes safety precautions to prevent the grenade from popping prematurely.
This is how you make a vinegar grenade. The first thing you need is two water bottles. We're gonna be saving the caps, so don't throw them away. Go ahead and pour out two lines of baking soda on two pieces of paper towel. Now we're gonna roll these up so they can fit inside of our cup. Now we're gonna fill up our water bottle with some vinegar. You don't need the whole thing, just go about halfway. Now we're gonna put our paper towel inside of our cup and then screw it on. Let's try it out. The trick is to hold it and shake it in your hand just a little bit before you throw it. Just make sure not to hold it for too long because then it will pop in your hand. And that would suck. Get back here, what are you doing? I wanted to blow it. All right, you see how it's completely smooth? There's a lot of pressure in here. Now when we throw it, it should work.
