I need it for science class,I want to make an airtight bubble to go underwater and actually sustain life.the oxygen would get to the bubble which would be on metal rowels glued to the bottom of the tank,any way the oxygen would get to the bubble with a tube system.basically the whole thing would be one big tunnel.as for what shape it is,I'd like it tobe pretty much half of a tennis ball.

For the life of me I can't see how we should know that from the original question. However your best - and perhaps only bet - is to do something like this.

and here

Otherwise a bubble of air free under water will form a ... bubble....

The only other option employed by the animal world is by certain spiders who entrap air in tiny hairs on their body BUT their O2 demand is very low.

Assuming Steve is right and that the packaging is a thermo plastic you could heat it up in an oven to about 130 deg C and then inflate it with an air compressor until it is the right size.

I suspect this "bend" in the same, weird sense of hacking circuits: so the OP wants to be able to form a bubble from waste packaging.

We need a photo of what you've got, and a sketch of what you want.
