A student built a real anti-gravity machine… using an Arduino. How to Make an Acoustic Levitator: Arduino Nano + motor driver + about 60 ultrasonic transducers. They all emit ~40 kHz sound. The sound waves meet and form fixed pockets in the air. Tiny bits of styrofoam get stuck in those pockets and just hang there. If you put your hand in, the pattern breaks and they fall. Same principle labs use to move droplets or samples without touching them.

🚨BREAKING: Davidson County Criminal Court Judge Cindy Chappell (D) sentenced Honduran illegal alien Aldo David Herrera-Andino to just five years of probation after he pleaded guilty to shooting a Tennessee man in the face. Herrera-Andino, released into the U.S. under Biden-era policies, admitted to firing the handgun during an altercation in Nashville. He left the victim fighting for his life and fled the scene. The charge was felony reckless aggravated assault. Judge Chappell, a Democrat elected in 2022 who previously worked in criminal defense, imposed the probation sentence and released him. ICE has since taken him into custody pending deportation proceedings. This is the same pattern of soft-on-crime sentencing that keeps violent offenders on the street. A man shot in the face received no prison time from this judge.
