because it did travel without the bag.

well an aircraft will take off as long as its payload is not too heavy.

because it was the last good balloon I had left and I didn't want it to break

yea SEE , I went through around 8 of the 12 in the pack
and I used the pump that came with them.

t doesn't have to be fancy, just get a normal balloon, a plastic bag, a pen tube, some tape, and a rubber band. That's all you need to shatter the world of physics and get a Nobel prize!!! Do it!

I think that something so earth shattering should be done properly , with proper documentation , thats why.

Those are made to higher quality standards and are more readily available than balloons, and can be inflated further. In fact it would probably be more effective because of the bigger opening.

I thought you agreed that a metal tank would be much better
I still think it would and that is why Im going to use one.

of course I could just make a tank out of 12 inch PVC pipe that would hold 420 psi because its minimum bursting pressure is 420 psi.

my compressor will only pump up to 130 psi.

so that should be safe enough.

3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
