By chance, a small experiment was conducted at home, the results of which were very interesting and surprising.
From nothing to do, the LED was taken and stuck in yogurt (perhaps these actions will seem silly to many, but the real experimenter is ready for any stupidity), as a result, the LED lights up. This was very unexpected, so further studies were carried out using various yoghurts: with peach, mango and other fruits, but no similar result was obtained for them. Only in strawberry yogurt did the LED light up.
Watch yourself getting energy from yogurt in the video:

Let's repeat this unusual experiment and see for ourselves that yogurt can provide energy not only for the work of our muscles and brain, but also so that a small light bulb emits real light. So, we need strawberry yogurt (why strawberry is difficult to say, but the fact suggests that yogurts of other tastes do not cause such an effect), one LED, a small incandescent lamp, two wires and a tester to check how many volts one yogurt produces.
First, take our yogurt and open it. Next, we take two wires and connect them to the LED (we fasten the ends of the wires to the contacts of the LED). Free ends are lowered into yogurt and watch the result. The LED lights up.
Let's try to light an incandescent bulb. Unscrew the wires from the LED and attach them to the lamp. We lower the free ends into a glass with yogurt, but, unfortunately, the light does not light up. Perhaps this is due to insufficient current or for some other reason.
Now let us check with a tester how many volts one yogurt produces. We set a 20 V tester, lower the terminals into strawberry yogurt and look at the result. The tester shows 1.44 - 1.45 V, but the value jumps a little.
Usually, LEDs are 3-4 V, but as you saw, our LED burned quite brightly, and the tester showed a little more than one volt.
I cannot explain the results of the experiment.I would like to understand why this happens, what there is in strawberry yogurt, from which the LED lights up and whether such yogurt is generally useful for humans. Maybe yogurt contains some acids that lead to interaction with other substances.
If you have any ideas why the LED in yogurt can burn, then let's discuss them together.
