First off - Iian, Absoutly amazing, Talk about thinking outside of the box (or
can :) )
Secondly:
If anyone has a scale to measure the weight of the cans, can you please bring
it, Also additional cans would be great as well...
See you tomorrow.

Who has a bot assembled, and is starting the coding...
