i have made an invention that will blow many peoples minds.if you have annoying brothers or sisters the you need the fart gun 2.0 it will do you very well. so how it works you have to get the container then you get the fart essence and load it into the container but make sure you have a mask on before you do it cause it stinks.then you load it into the gun
but you have to prime it back to load it. then you go to your brother or sister then you say time to stink then you shoot it and then you pull the trigger then they really stink
