Hi Eric,
The best "whoosh" bottle is made by sealing two nails on oppsite sides of a
polyethylene reagent bottle so that they are about one centimeter apart. Put
about 5 ml of METHANOL in the bottle and stick a rubber stopper firmly in the
mouth. Bring a Tesla coil leak detector up to one of the nails and BOOM!. The
rubber stopper will pop out of the bottle harmlessly if aimed upward. I have
done this demo many times with same bottle with no problems except for an
occasionly lost stopper. The nails can be sealed with silicone sealer.
