This is the way I learned: 1. Take a plastic dropper and cut off all but about 2cm of the long end 2. Take a metal nut and screw it on to the 2 cm 3. Place it in a nearly full bottle of water, nut end down 4. Put the cap on Squeeze to make it dive and let go to make it float
Because if you don't squeeze it, it won't fit together and it will be a pile of snowflakes. You can't really make a snowball/ball if you don't squeeze it. If do it will just crinkle up and break.
because all the space in the syringe is taken up by water. If you squeeze the syringe it will break.
Because is dangerous
The purpose of a dropper pipette is to administer only a small drop of a liquid to something. The dropper pipette is a tool that will allow you to squeeze a single drop of the liquid it contains.
A dropper simply is a small tube with a air-filled bulb at the top. You squeeze the bulb at the top and whatever substance the tube is submerged in, it will be pulled up into the tube. After that, you lightly squeeze the bulb again to release the substance in the tube out.
According to an industry journal, it was April 8, 1956 that the first squeeze bottles where used in diners and restaurants for dispensing ketchup.
If you squeeze the bulb to expel most of the air, then release it with the tip under water, the pressure in the bulb drops and external air pressure on the surface of the liquid in its container forces the liquid into the dropper. When you squeeze the bulb again, you increase the pressure and force the liquid out.

If one is looking to purchase squeeze bottles, you have a few choices. You can try Walmart or Target, they can be found for about a dollar. You can also find them in many sizes at the Dollar Tree.
While the results vary for dropper size and the force you use to squeeze the dropper, you should conclude that water has a high surface tension and the penny held a lot of water.

Squeeze bottles make it easier for a viscus product to be used. The squeezing action forces the liquid through the narrow opening making for a more controlled use of the product.

2 drops... if you have a dropper (one of those things you pinch to suck up water, and squeeze to drip out), simple squeeze it gently twice until two single drops come out.
