Onderwerp: attack of the killer bubbles
ISEN-ASTC-L is a service of the Association of Science-Technology Centers Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
to those of you who have a large-scale bubbles exhibit:
I'm having a bit of a debate with the Building Manager here at BCM. I'd like to add glycerin or a polymer to 2 of the stations in our exhibit. I was summarily shut down with the reason that the glycerin would cause even more problems with the pipes. I argued that I was talking about 1 capful at each station (one station holds about 3 1/2 gallons, the other holds about 10), and at this dilution, it wouldn't really make a difference.
so my question is...
do you add anything to your bubble solution to give more staying power? if so, what is it, and does it mess with your plumbing?
thanks all,
Alissa
