When Bianca goes to the skate park to watch her friend Kim practice skateboarding, she runs into Tony – a cute boy on whom she has a huge crush. Bianca wants Tony to notice her, but Tony seems to be focused on Kim’s impressive skateboarding skills. Not to be outdone, a jealous Bianca attempts her own skateboarding tricks – and ends up with a broken ankle! While recuperating, Bianca has trouble reaching things, but a gift from Kim helps make life easier – a device made of hinged pieces of wood. Because the pieces of wood form parallelograms that lengthen when flattened, the grabber allows Bianca to pick up things that would have been beyond her reach.
