Now the great dream of mankind, to float a spider, can finally be realized!
If you’ve ever dreamed of suspending a spider in thin air or floating an ant in midair (and who hasn’t?), new research has your back.
In a new open-access paper published in the journal Review of Scientific Instruments, researchers from the University of Bristol in the United Kingdom lay out the instructions for making an at-home acoustic levitator. The gadget requires a microprocessor called an Arduino (available online) and access to a 3D printer, along with a few other pieces of hardware. The result is a device that uses the pressure of ultrasound waves to “float” tiny objects like water droplets, Styrofoam dots or even insects.
