Lishtot’s TestDrop tells you water is safe without even touching it

Lishtot’s TestDrop tells you whether water is safe to drink without even touching it
Consistent access to clean water is something billions lack, and part of that is the inability to check whether one’s water is clean or not. Lishtot could help change this with a tiny device that instantly determines if water is safe to drink just by analyzing the electric field around it — no strips, no microfluidics, no toxic chemicals. It honestly sounds too good to be true, but as far as I can tell it’s the real thing.

                                                                                                       The device has been subjected to third-party testing, two reports from which I read; the thing really works. It detected even tiny amounts of lead and protein instantly and with 100 percent accuracy and no false positives or negatives.

The replaceable watch battery should last for years even if you’re using the device 10 or 20 times a day. Several of these known readings are built-in (it’s calibrated around half a plastic cup of water, as the plastic doesn’t interfere with the fields) and the TestDrop doesn’t need to check its data against the cloud in order to give a drink/don’t drink response.
