Birthday party part 3

Lukas wanted to host an overnight programming, robotics sleep over to celebrate his birthday, so Sunday afternoon, we 'gained' two young men and the four of them headed downstairs,  There was pizza baking in the oven, chips and snacks on the counter and ice cream in the freezer.
Bob spent several hours with the four boys as they work on the robotics challenge. When Bob was not downstairs helping them, he was in the garage building yet another structure for the playing field.
When the two boys left on Monday afternoon, there was no more soda, a cold dry piece of pizza, empty ice cream containers and a trashcan full of candy wrappers. Most of them were proud to declare they did not sleep a wink. A fun way to cap off the 14th birthday celebration.
