Air delivery system using pvc Answered

Hi,
I am a geocacher and I recently saw a youtube video of a cache container that was a 2 inch PVC pipe.  At the bottom, the cap had a tire valve in it.  When you pumped up the container, a pill bottle came out the top.  I have attempt to build something like this but nothing seems to work.  The pill bottle will not rise.  Can anyone help me with what I am doing wrong?

Thanks,
Kent

Slightly related: I saw a good one where by holding your hand over the bottom of a pipe and filling it with water, the cache would float to the top.
