Build and play through your very own mini-golf park -- with LEGO bricks!It's a hole-in-one lotta fun! Learn about the science of the golf swing with a whimsical desktop-sized mini golf course. With everything you need included in this kit, you'll engineer a mini golf course hole, play through with the included mini balls and D.I.Y. putters, and then unbuild it to make the next hole. One at a time, you'll build nine holes in all! LEGO obstacles like a mini windmill, pirate ship, an octopus, and other quirky features can be interchanged on the boards, which include green and blue felt, as well as easy papercraft bridges and an amazing loop-de-loop! Easily switch in different LEGO obstacles to change and modify each hole and extend the play value. Challenge your friends to score a hole-in-one (or at least get under par) and snap a photo with the winner's mini golf trophy (also included, of course). Explore STEM concepts like torque, velocity, and vectors to help you master tricky traps and perfect your shots!
