I normally use ordinary glassware and use the camera on the laptop to project it on the screen to show the students in the lecture hall.

>> I'm looking for a 4L filter flask for a demo but they all seem to be $150-$250. We are creating a vacuum in order to boil water. It needs to be that big because of the size of the lecture hall. Does anyone have a good website to turn to for glassware like this?

I can find 4L flasks for under $100 in our on-line discounted pricing. And because of the purchasing power of our University, their sales staff may discount it even further if I ask for a formal quote. Also note that most E&I's waive shipping so make sure you find it at a discount house double check the shipping.
