Taskmaster Tasks

Build the lightest tower on this set of scales.

Build the lightest tower on this set of scales. You may not move the scales or tape anything to them, and you may not tamper with or block the fan. The fan will be on for one minute every other minute. 

At the end of ten minutes, your tower must be taller than a wolf and stand by itself for ten seconds. 

Lightest tower wins. 

Your time starts now.
