but I must ask: isn't the demo below pushing the envelope of safety?

3) A little liquid N2 poured into a small plastic container, screw-on the
cap, toss it into a strong metal bin filled w/ water. The nitrogen changes
into a gas, pressure increases and the bottle will explode. Move way and
make sure that you're not near the audience. Small bottles (shampoo bottles
from hotels) work well. The bigger the bottle (soda bottles), the bigger the
explosion and the danger. Wear gloves, goggles and ear muffs.
