As long as you change the stance of the pilling tissue, will it not be wet in the water?| Play

Strange knowledge has increased again

experiment equipment

Bid cups, small cups, paper towels, water basins

experiment procedure

First of all, we stuffed the paper towels into a small toast

Then, put the burn cup inverted into the water basin full of water

Pay attention to the cup mouth as much as possible on the water surface, don’t tilt too much

Take the small burn out of the water basin

Finally, take out the paper towel in the small cup

You can see that paper towels are not soaked by water

Original understanding

When we put the cup buckle into the basin, some air is sealed inside the cup. The air pressure of this remaining air will prevent the water from entering the cup, so the paper towels will not be wet.

However, if the water basin is deep enough, when the cup is gradually pressed into the bottom of the water basin,

According to liquid pressure formula:

The pressure on the air in the cup will be greater. The air inside the cup will be compressed. The water will gradually enter the cup until the water pressure is balanced with the air pressure in the cup. At this time, the paper towel will be wet.
