OK, perhaps someone can help me.

Think of the following experiments: you drop a piece of burning paper
into
an Erlenmeyer flask, then put a balloon over the top which gets pushed in
by
air pressure. Or you use liquid nitrogen to shrink a whole bunch of
balloons
into a beaker, they re-expand when you take them out to warm up. Both of
these demos require hot dog shaped latex balloons. Not round ones, not
the
super skinny type used for balloon animals... hot dog shaped balloons.

Where in the heck can one find these things???

Help!
