The Sprinxer is a vehicle for transporting a gummi bear from A to B. It had to be made of shashlik spits, wooden rods of 198mm length and 3mm in diameter. Only the usage of thread was allowed to connect the rods. The apparatus was to jump over a 45cm high barrier, carrying a small load, and had to be reusable. This solution works like a crossbow that shoots itself and its load. A minimum of rods and connections makes the Sprinxer even cheap and easy to produce.
