Air cannon Answered

After wanting to make an air rifle for awhile I have finally decided to do it.  I plan to use 80-100 psi from a bike pump to power it.  I plan to use a 1/2 or 3/4 inch QEV (something like this https://www.amazon.com/uxcell-Pneumatic-QE-04-Inlet-Exhaust/dp/B01MYRC509/ref=sr_1_12?ie=UTF8&qid=1495573897&sr=8-12&keywords=3%2F4in+quick+exhaust+valve).  Do you guys know if a 2L soda bottle would be a good air tank or should I spend the money to make a pvc or galvanized steel one?  Would an air gun connected to the QEV work well? 

Thank you for your time and help

both soda bottles and pvc are bad ideas for compressed air in my experience. Details later.

I've had 2 soda bottles rupture on me.

Have experienced 1 catastrophic failure with pvc and air,

I personally know people with 2 other pvc failures.

Pvc shards are sharp.

Don't depend on luck.

30 psi is probably OK, but...

Google how many psi a soda bottle can handle before bursting. If you're planning to use it a lot, make sure it's higher than what you want to use. Replacing them all the time might not be fun, but I don't think that having them explode in your face is too... :)
