Be able to conduct experiments to demonstrate Bernoulli's Principle. Introduce the students to Bernoulli's Principle as it relates to fluids and gases. Holding it in place, blow over the top of the paper. Try placing paper clips on the hanging end of the paper and see if it has enough lift to overcome their weight. This makes it so that the paper has higher air pressure underneath it, lifting it into the air.
Student blows between the two sheets of paper.
Paper will be attracted like magnets. The two pieces of paper will come together. Bernoulli's Principle is applied. The increase in air speed between the two sheets of paper causes a decrease in the pressure, allowing the higher air pressure on the outside of the two sheets of paper to push them together. Place spool over point of the tack.
