One of them wants to go back in time, one has been banned from experiments at home and one has to eat rock buns. Called to the challenge, the whizzes in a breathtaking episode build the most toxic-free lava lamp with shower gel.

A weirdo pursues Flash. Mr Ch'ng needs help - he has given his wife's undergarment away by mistake. And it's a wife from hell. Desperation and fear dominate the situation - will the kids ever get to finish the steam engine?

The households in the neighbourhood suddenly find that their umbrellas have gone missing. The kids now have the task of finding the culprit. By the end of the day, the Whizzes have built a planetarium, launched a water rocket and totally exhausted.

Flash has a crush. But it's a crush that may have dire consequences if he doesn't smarten up. Making bath bombs and soaps are easy, but will the fart-nappy really help? And who drank the love potion?

An old man is suicidal. He believes death is calling him. The kids think it's just radio waves. Will the kids complete the crystal radio before the old man kills himself? And while the kids are gone, did an UFO come calling?

It's back to the 70s for Mr Ch'ng but the 70s was a long time ago. Dynamo Ch'ng can no longer move the way he did unless... Stuck with a bothersome kid, the Whizzes are involved in animation and perception: A deadfish floating in a bowl, a Devil's Wheel and a boy-eating alien - all fail to satisfy. So how can a simple kaleidoscope do the job?

Was the ball lightning for real? Who is to know. Electric circuits, lightning and electromagnetic motors all have a pull on this episode, culminating in a film noir experience for Gene as he attempts a dangerous experiment and has to pay the price.

The whizzes face their second challenge - a young magician wants their space and now science and magic pitch battles in the void deck. Forced to explain a wide range of magic tricks, the whizzes have no choice - they made the magician disappear.

The whizzes are led on a wild goose chase after they receive a secret message. Through barcodes, morse codes, a code-maker, they discover the world is not everything it seems to be. But who is sending the SOS?

The search continues - still unable to solve the mystery SOS, the whizzes embark into the world of sound. Is Weirdo in need of help? How can a vortex generator, a boing thing, a twang box, a sound telescope possibly help?

The whizzes face the biggest challenge of all: one of them betrays the group and now all three children are put to the test. The Committee Meeting takes place and the future of the Whizzes hang in the balance. All they have to show are a few machines : the anti-MC, the hypnotizer, the bubble machine and the robotic arm.

MC begins a Captain's log and it takes us on a journey into the small world of micro-organisms: crystals from blue dye, stalagmites and stalactites, a water magnifier and a home made microscope. But they are jolted back to the big picture of life as the old carpenter reappears. He takes them on a journey back to his childhood days. An episode that is very weird, a little creepy and somewhat sad.

It's the day of the Flying Thing Competition and the whizzes are being whizzed out with things that glide, hover or fly. With the help of the Origami Samurai, they make a record-breaking paper plane, a drink bottle glider, a hovercam, an origami kite and an amazing plane powered by the housefly. But, by the end of the day, one of the whizzes will disappear.
