A new box of objects means three new inventions. This week it's a jar of BBQ sauce, a cigar, and block and tackle. First, Bob builds a machine to help first-time cigar smokers light their stogies like a pro. Next, Bob uses the BBQ sauce in a machine for a new restaurant that needs a real BANG! to put them on the map. Finally, the team uses the block and tackle to free up some space in Bob's cramped shop.
