I'm going to be doing Jekyll & Hyde in a couple weeks and I've been trying to come up with a good way of making the laboratory come to life. It's such a big portion of the show I really want to make sure it comes out right. As of right now, I plan on lighting up some of the glassware from underneath the counter top with a handful of those little puck-shaped under-counter lights. I'll either gel the pucks or just use food coloring in the water to give some color (or both). I'd really like to get some of the equipment to bubble and whatnot, but I'm not sure the best way to do so. I can't bring actual bunsen burners into play, that has disaster written all over it. It's a high school production, so I'm trying to stay away from any real fire. I've been thinking about using those little air pumps used for fish tanks and just running some tubing into the equipment. Either that, or we have a compressed air tank (just the tank, no motor) that we can hide inside the lab bench itself. It's large enough to last the whole show and I figure that might be better so I don't have to deal with the noise generated by the pumps. I'm curious what other people have done for this, or similar situations. Any suggestions?
