@museumofscience You can inflate a plastic bag with just three breaths using science! 💨  @Alex Dainis 🧬🔬 demonstrates how to do this with Bernoulli’s Principle, which explains the relationship between airspeed and pressure.  #PhysicsTok #GetCultured #ScienceTok #BernoulliPrinciple
A science expert on TikTok has been getting hits with her easy party trick to fool your friends. Â She shows how you can blow up a plastic garbage bag using only THREE breaths.
The trick is to NOT blow into the bag like you would a balloon. Instead, you back up from the hole in the bag, and THEN blow into it.
Your fast-moving breath rushes into the center of the opening of the bag causing an area of low pressure. The surrounding air outside gets dragged INTO the bag. Basically, “you’re multiplying your efforts.”
