Measure the Resistance of Your Tongue

I actually don't recommend measuring the resistance of your tongue with a multimeter, because who wants to stick a pointy object in their mouth. You may still want to do it, just be careful.

This is a very basic experiment which will teach you about measuring resistance and it will also teach you some unique characteristics about resistance in regard to dryness or wetness of a surface or area. In this experiment, we will use a multimeter to measure the resistance of your tongue in two conditions.

The first condition is when your tongue is moist. Make sure your tongue is moist and wet, and take the multimeter probes and place them on your tongue an inch apart. And check the reading. The reading should be somewhere near 50KΩ.

Now, for the second condition, dry your tongue of all the saliva. Now place the probes back on your tongue an inch apart. Now the reading of the resistance will be much higher.

This experiment proves that resistance is lower in wet conditions and higher in dry conditions. This is because water, in a way, is a conductor. Since it lowers the resistance of a path, it allows current to flow easier. Also now from this experiment, you now know what the resistance of your tongue is in these two different conditions.

This is also the reason why water, if you get into an electronic device, such as your iPhone, can cause it to short out. Water is much more conductive than a dry surface or area. If you water into an electronic device, it can short components in the device and cause it to work anymore.

So, more than anything, this experiment goes to show you this point that water lowers resistance.
