So, I just purchased this: I'm making a crazy scientific flask ant farm for my husband's birthday, and this will be the center piece of it all. I know this is a round scientific flask...distillation flask I think...but I've never seen those little arm-ish things around the base. Can anyone help me out here? I'd like to be able to tell him what those are for when he asks. XD The indents on the side aren't something I've seen in that shape before, but I'm guessing those just increase agitation of liquids like normal indents do. There wasn't much info for it. Just that it is made by Tudor Scientific. Couldn't find the blasted thing on their website though.
