My chem teacher had us make eye-droppers from glass tubing. I put one into the rubber tube & hooked the other end to the water faucet. It’s amazing what kind of distance you can get with basic water pressure forced through a smaller aperture. Extra credit in Physics, but a visit with higher authorities in Chemistry. We also enjoyed stink bombs.
