What is the best way to inflate an 8-ft-long, 10"-diameter bag? With just 1 breath! Traditional methods used to blow up a balloon or paper bag can leave you winded. Instead, blow 1 long breath straight down the middle and the bag inflates in seconds. Challenge students to apply Bernoulli's principle to explain why a fast breath applied at a distance works best. Includes 4 bags and instructions.
