Lishtot's TestDrop tells you if the water is drinkable without even touching it

Regular access to drinking water is one thing that is missing in the billions, and part of this is the inability to check whether the water is clean or not . Lishtot could help change that with a tiny device that instantly determines if the water is drinkable by simply analyzing the electric field that surrounds it – no tapes, no microfluidics, no toxic chemicals. This sounds honestly too good to be true, but as far as I know, that's the reality.

I spoke with Lishtot (CEO of "drink" in Hebrew) at CES, Netanel Raisch, where he demonstrated the simplicity and efficiency of the TestDrop device. He had with him two plastic water cups, to the one of which had been added a contaminant. By pressing the test button, he moved the TestDrop to a clean, blue cup – light. Do the same for the other – red, contaminated light.

It's as simple as that to operate. I did it myself successfully after one or two tries. That's so simple, in fact, that I was suspicious. I thought it might be a kind of spectroscopy, but where was the transmitter? Why did you have to move it, if not to create a kind of Doppler effect?

It turns out that everything is based on the electromagnetic fields that surround everything. The water creates its own local field, which is measured by moving the TestDrop through it, and it turns out that clean water emits a slightly different field of water with lead or chlorine, water with E. coli, water with materials and so on.

The device was subjected to testing by a third party, two reports that I read; the thing really works. It has detected minute amounts of lead and protein instantly and with 100% accuracy and no false positives or negatives.

The battery of the replaceable watch should last for years, even if you use the device 10 or 20 times a day. Many of these known readings are embedded (it is calibrated around a half-cup of plastic water because the plastic does not interfere with the fields) and TestDrop does not need to check his data against the cloud to give a drink / not drink answer.

However, if you want to import the smartphone and the app, Lishtot runs a service that tracks the tests done with its devices, if users choose to send them. Raisch hopes that this will become a useful database for both ordinary users (who can find sources of clean water if necessary) and for governments or businesses (who can exploit and monitor trends). You will also be able to report problems directly to the utility.

Lishtot has more technology related to the purity of water on the way, but for now the TestDrop is its main product. The devices cost $ 50 each, or $ 35 with the CES discount – but I suppose that they are more likely to spread when they are purchased in bulk by NGOs, utilities and public utilities. other organizations, distributing them where they are most needed. ]
