Experiment Of The Week – Cup Blowing Challenge

Take The Cup Blowing Challenge

It’s one of the newest challenges you’ll find on the world wide web. Jason Lindsey aka “Mr. Science” with Hooked on Science and a local kid scientist show us the science behind the Cup Blowing Challenge.

“Music” What are we doing, you’re probably wondering that, right? My science helper, Ethan and I are tying the newest challenge to hit the world wide web. It’s called the cup blowing challenge. I take one empty cup, place it into another, put one cup in front of those two cups and try to get the cup on the inside, into that one. Let me try it here again. Almost! Did you see that, I did it! There is a science behind this, I promise. Ethan, what’s lifting that cup up out of that one into that one? My breath! Good job! What’s pulling that cup into the other one? Gravity! Good job! Give me five for science. You’ve got to try this. Learn a little bit about science, while trying a challenge that you might find on the world wide web. You can learn more at hookedonscience.org. “Music”

Cup Blowing Challenge

INGREDIENTS

  • 3 Cups

INSTRUCTIONS
STEP 1:  Place one cup inside of another.
STEP 2:  Sit the cups on a flat surface. Place the other cup directly in front of the two cups.
STEP 3:  Using your breath, gently blow the cup, inside the cup, out and into the empty cup.
STEP 4:  Repeat steps 1 through 2. Using your breath, blow the cup, with more force this time, inside the cup, out and into the empty cup. Compare the effects of different strengths of pushes on the motion of the cup. Provide evidence that a pattern can be used to predict the future motion of the cup, inside the cup.

EXPLANATION
As you blow air between the two cups, your breath lifts the cup inside the cup, up and out of the cup. This forces the cup into the air and if you do it just right, gravity pulls the cup into the other.
