Quill claims to have mastered the art of unaided aviation, but his attempts to prove it leave Beamer and Mouse unimpressed. Meanwhile, the Professor shows us how to make a coat hanger mobile, we watch some birds, hot air balloons, helicopters, and Concordes on the Bubblescope, and Chromety sings a song about a bumblebee and tells us a story about Sam and his home-made butterfly. Good wholesome fun, as ever, aimed squarely at those born in the late 80s or early 90s.

Huge thanks to Joe for lending me this tape.
