Pull the middle sticky pad from a stack¶
Objects¶
- three shrink-wrapped 3 x 3 inch sticky-note cubes (Post-it Super Sticky notes cube or equivalent)
Setup¶
- Stack the three pads vertically at the centre of the bench.
- Offset each pad slightly (about 1 cm and a few degrees of yaw) from the one below so the edges are not flush.
Instruction¶
There is a stack of three sticky notes. Take the middle one out and put it on the table. Make sure everything is at rest at the end, but do not let the top one touch the table at all, so it should rest on one of the sticky notes at the end.
