Why does water form beads on a table?
It turns out that this surface tension is the result of the tendency of water molecules to attract one another (called cohesion). … When cohesion is more of a factor, the water forms spherical droplets; when adhesion is more of a factor, we get sheets of water.
Why does water flow together and collect as droplets or beads?
This occurs because water is made up of many tiny molecules that are all attracted to one another. Molecules in the middle of a drop of water are pulled evenly in all directions by all the nearby molecules.

What happens to the water droplets as you roll them around on the wax paper?
Waxed paper pushes water away and does not absorb it. The surface tension of the water pulls it into a little round blob; these blobs, or drops, can slide around waxed paper because the paper does not absorb it.
What happened to the drop of water when you touched it with toothpick?
Water molecules have a strong attraction for each other. … But when you dip the toothpick into dish soap, the water water is repelled, not attracted, so the water bubble bursts as it tries to move away.
