Welcome everyone
Children's program, some have decided to teach the children a model.
As I know from experience that a carnival atmosphere in which it is difficult 10, 15 minutes to engage your attention, simply built a rubber powered model designed for them.
Here's the prototype.
If someone in this category would be more ideas, please share it because they want to employ throughout the summer for children.
In the meantime, my sons the gift is completed.
Sincerely Elf Daddy
