We're having our reception at the local science museum, so we don't need a ton of decorations. The coordinator there said most people just use table decorations. I'd like to have some fun, science-themed table decorations, and maybe some fun interactive science kits on smaller tables around the reception area (they do have small tables they are willing to leave out during the reception). Any thoughts on how to accomplish this without bordering too much on cheesy and super theme-y?
