On behalf of a colleague...
Hi everyone,
Apologies for cross-postings.
Questacon is developing an exhibit on refractive indices.
Visitors lower different types of glass into glycerol and see that some of them disappear.
We would like a lowering mechanism that is quick enough to hold our visitors' attention but doesn't cause bubbles which destroy the effect.
Has anyone got any ideas?
Thanks,
Wendy
