Two Coke bottles are stacked with a dollar bill in between them and water in the top glass. When the dollar is pulled out, the bottles remained stacked and the water drains into the bottom glass. This can also be done with out the water. Both demonstrate inertia just with a different mass on top.
* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.
Setup:
Stack Coke bottles with dollar bill in between them. Quickly pull the dollar out.
This can be done with water in the top bottle as well. The increase weight on top makes it a little easier and it looks cool! Fill one bottle with water. Place the dollar on top of this bottle followed by the other bottle. Carefully turn over the system so that the filled bottle is on top. Quickly pull out the dollar. The water will drain into the bottom bottle.
Notes:
It may be easier to strike the dollar downward with a pen to ensure a smooth pull.
This demonstration requires some practice ahead of time.
This demonstration has an alternate version. Based on your proficiency, it may be easier to do this version or the other, or both. They demonstrate the same concept.

Discussion and Polling Questions:
Why can't we pull the dollar bill out slowly?
What if we replaced the dollar bill with a rubber sheet? What physical quantity would change?
How does the bottle being filled/not filled with water change the demo?
