Acoustic Levitation ✨👁️🪄🪬 — Transcript

Full transcript

1. 0:00If you know that frequency, you can
2. 0:01control things. This is the math and
3. 0:04this is diagramming all the frequencies
4. 0:06of the elements and what their
5. 0:07vibrational frequencies are and the
6. 0:09numbers that measure those frequencies
7. 0:11and they're all the numbers we get from
8. 0:13looking at these ancient traditions that
9. 0:15recur over and over and over again.
10. 0:18>> And so through somehow
11. 0:21through this technology, they're able to
12. 0:23move stones or cut stones or all the
13. 0:26above? All the above.
14. 0:27>> We call these transducers,
15. 0:29which is a fancy word for speakers.
16. 0:31[music] These are speakers they only
17. 0:33work at one frequency and this frequency
18. 0:34is 40 kHz, which we shouldn't be able to
19. 0:37hear. Only bats, dogs and other animals
20. 0:40should be able to hear 40 kHz, but
21. 0:42because the ultrasound is so powerful,
22. 0:44if we put some particles, they should be
23. 0:47kept in midair with the power of sound.
24. 0:52And all this stuff that they are just
25. 0:53being like kept there with air, actually
26. 0:55it's not air, it's the
27. 0:57ultrasound pushing them from all
28. 0:59directions.
29. 1:11>> Scientists already knew that sound waves
30. 1:13create oscillating pockets of
31. 1:15pressurized air, which can produce a
32. 1:17force on an object capable of
33. 1:19counteracting the pull of gravity. But
34. 1:21while ultrasound levitation devices do
35. 1:24exist, they all rely on standing waves
36. 1:27created when two sound waves of the same
37. 1:29frequency are emitted from opposite
38. 1:31directions and superimposed on one
39. 1:33another. That means all previous devices
40. 1:36required two sets of transducers.
