Hey your smart dude. Lately scientists have made a rodin coil and pulse dc at 144k That the water droplet will levitate and spin. This is how ufos fly. They have spinning fields round them; pulse dc at gigahertz or higher. Fasf enough to ionize the air and glow blue or faster; white.

Now I'm curious. Is there a way to make multiple close semi circles and make a drop shoot up an incline. Like a boost ramp from a video game lol

[@MrGoatflakes]

Yes but no. You could make it go wherever you want, but the drop of water isn't going any higher than the height you dropped it from. Unless you have a little bit break off then that little bit can rob energy from the rest of the drop which just goes up a little bit. Like weakly sticking a squash ball to a bowling ball. The squash ball can go flying. You could have a real boost ramp by imparting other energy there. Like potentially vibration or boiling, like directed Leiden frost effect 🤔

[@MrStuart21]

If you are ever taking a shower in sunlight, you might notice that the water drops look to be a series of dashes - This is because the water squirts through the hole, & coming out as a cylinder, but then surface tension pulls it back together as a sphere - then it bounces between the two, - & light passing through appears togo 'on / off on off etc . You can also simulate this in the garden with a hose.
