Each student will have 2 attempts to create a cookie stack.
Students will place one cookie on the paper plate/table cloth and add one cookie at a time to the stack.
Students may NOT adjust the cookie after they have placed the cookie on the stack and moved their hand away.
Cookies need to be freestanding and NOT leaning against any kind of support or use any kind of adhesion so they stick together.
Cookie needs to be a regular cookie and not separated in ANY way.
Another student should be tallying as the student stacks.
A tumble has occurred once 1 or more cookies have tumbled off the stack. The complete stack DOES not need to completely tumble for it to be called a tumble.
