I'm planning to make a toy gun that shoots nerf darts. What is the maximum allowable safe pressure for a drink can or PET bottle. The holes will be sealed with hot glue.

Thanks in advance.

I have a Nerf Long strike that uses a reverse plunger system. I am looking up on how I can mod it. Net blogs and forums mentioned something about dead space in the plunger and removing it by filling up the space. Can anyone tell me where is this dead space in the plunger?

Please give your comments.

I'm a guy and when I get too angry over 5min, I start to cry but I'm still angry and I let my emotions go more easily resulting in more shouting.

I am trying to understand how the bonding in diboron between the bridging hydrogen and boron atoms exist and looks like in simple terms. (I only have up to sigma-bond pi-bond, hybridisation level of knowledge)
