Well I'm really hoping that Jose tries the card thumbtack soda straw
thing.
Actually, I did try it and it didn't "work" (that is, the card didn't
float, which is what I think you expect to happen). I'm probably doing
it wrong so I'll keep at it. When I get it to work, I'll report what
happened and why (in newtonian terms) I think it did.
Well after reading that I went and tried it myself and blew the card
off the end of the straw so I must be doing it wrong too!
I've known of this trick from childhood, (yes, I realize that some
of you are thinking that could mean I first learned of it a few days
ago) so by now I can't remember exactly how or even if I did it
myself. Memory is like that.
Could we reduce the crossposting? I think one newsgroup is more
than sufficient. You chose, and I'll follow.
