Experience Hydrodynamic Levitation: A Simple yet Mesmerizing Effect

Click For Summary
SUMMARY

The forum discussion centers on the phenomenon of hydrodynamic levitation, specifically highlighting a simple effect that can be reproduced using an air jet. Participants noted the effectiveness of an empty plastic bag spinning midair due to an air updraft, and contrasted it with a water jet that was primarily vertical. The discussion emphasizes the versatility of the effect, as it can also be achieved with an angled air jet.

Here is a fun effect. I wonder if it has been described previously, given how simple it is to reproduce. I remember seeing similar effects with an empty plastic bag, spinning midair on the side of an air updraft.

Very cool. Thanks for posting.
 
Cool but their water jet was mostly vertical. I've seen it done with an air jet leaning at a considerable angle and it still works.
