A 10” wide, 8-foot long tube that is an excellent demonstration of Bernoulli’s principle. Using conventional wisdom and a good set of lungs, you can inflate the balloon using 70-80 breaths. However, if you are paying attention in your fluids class, you can inflate it using one or two breaths. Great demonstration, even better magic trick. Colorful and made of durable plastic, you can even connect the tubes with rubber bands to create structures.
