Ultrasonic levitation — the practice of creating a standing wave between two ultrasonic sources and positioning lightweight objects such that they can float in the pressure minimums between them ...

For those unaware, laser levitation is probably as close as we ... synthetic diamond powder works exceptionally well for this experiment. At about $1.60 a gram, it won’t break the bank either.

This enables the scientists to process the sample without contact to a crucible and with low magnetic field strengths compared to ground-based levitation. EML is located in the European drawer ...

MAGNETS! His page features over 100 magnetic experiments and games. He makes ASMR videos of magnets, and he has some levitation tricks up his sleeve. He also combines magnets with slime.

further experiments at the EPFL facility will seek to validate more efficient versions of the LIM-based hyperloop propulsion ...
