Mosquitoes turn pleasant summer nights into itchy ordeals for anyone spending time outdoors. One inventor refused to accept the usual sprays, candles, and frantic swatting as the only options. Instead he created a full-body electric grid that delivers a direct shock to any insect that gets too close. Russian maker Dani Cruster, who runs the DiWHY YouTube channel, drew inspiration from ordinary bug zappers. Those devices use two layers of mesh or grid with high voltage running between them. When a mosquito flies into the space, it completes the circuit and ends its life with a sharp crack. Cruster simply asked what would happen if someone wore that same grid.
