Pen, Hoop and Bottle
- Balance the hoop on the glass bottle as shown. Carefully
place the marker on top of the hoop, directly over the mouth of the bottle.
Swipe the hoop out from underneath the marker with one quick, horizontal motion.
Marker should fall directly into bottle.
- The two tricks to doing this demo successfully are: 1) placing
the marker directly over the mouth of the bottle, and 2) making a clean swipe.
The hoop is marked on the outer and inner rim to help with marker placement.
Make sure your swipe has no vertical component. Practice this one a few times
before using it in class.
