I came into the kitchen one day, recognizing and enjoying quiet. This was the site I found:
The boys were concentrating so intently and being so quiet, I was curious as to what they were up to!
Why would they be staring at a top and porcelain chicken? Funny!
So they told me to try it too, and began explaining the experiment.
First you need a top:
(this was a cheap top one of the kids got as a prize from Chuck-E-Cheese-nothing special)
Second you need a still item, they used this chicken:
Watch the top as it spins, staring at the middle for awhile:
Then try to focus on the still object:
It tricks your eyes into thinking the item is growing or shrinking in front of you!
Not kidding, it actually works.
Try it!
