I kind of feel like taking a 20-mL screw-capped vial, putting 1 mL of ether inside and placing it on a small heating plate set to maximum power, covered with a big plastic beaker. Any bets?
here is a better one: take a soda plastic bottle, add some dry ice, put the cap back on and watch from distance...
Grad students have been fooling with liqid nitrogen in one physics lab late at night - they filled a large 2L soda plastic bottle with N2(l) and put the cap on. As the pressre inside increased they could not unscrew the cap. They panickad and put the thing in the sink in mens bathroom - the bottle soon exploded and shattered the sink. The campus police arrived. The cops called up their advidor (who was already in the bed) and informed him excitedly that his students blew up his lab with nitroglycerine. He arrived promptly and when he saw the broken sink and was understood what happened, he calmly told the cops: "That's a part of the experiments." Then he went back home.
I bet on the ether

By may calculations, assuming a modest temperature of 100°C the 1 mL of liquid ether would want to fill a volume of 293 mL at 1 atm as a vapor.
If confined to a 20 mL vial at 100°C, the pressure would be about 14.6 atm (215 psi) assuming ideal gas behavior which it most certainly is not.
Realistically, at max power the temp will be higher than 100°C. My Corning hot plate manual says the temp at max power would be about 480°C. If the ether were to get that hot, the pressure would be almost 30 atm (400 psi).
My money is on the ether. Say good-bye to the vial.
Flash point of ether = -40'Cfemme_exotiqueFebruary 6 2008, 04:33:56 UTC
And autoignition point = 170'C...
So the fate of the beaker or of the vial would be the least of your problems, I am much more concerned about the possible destruction of the hood...
As one of the famous Beavis and Butthead disclaimers went, one could get "hurt, expelled, arrested... possibly deported. To put it another way, don't try this at home."

I only don't get why would the cops say that the lab was blown up, not the sink
