Labchaikovsky is an extremely clumsy piano maestro. He also looks a bit like a Lab Rat in fancy dress. Anyway, he's so clumsy he's actually managed to break more than 1000 pianos in his career. So, how can the Lab Rats protect Labchaikovsky's prized musical instruments? To find out they undertake an experiment in true Blast Lab style... Two pianos are dropped from a height of 30 metres onto two different landing areas: a trampoline and a bouncy castle. But which will be the best protection for the pianos?
