Welcome back to the learning pod. Get ready to absorb ALL the knowledge. Stevie has brought another batch of creations from throughout history, and it's up to Jaack and Robbie to decide whether they're strokes of genius, or deeply cursed.

We learn why it's probably not very smart to drink radioactive medicine. We hear about how a bloke from the 14th century tried to get to the moon. And we discover the device that will revolutionise your baby's mealtimes.

There's a solution (that might save lives but ruin yours) to stop people setting off fire alarms as a prank, and a creation so terrible it was discontinued before it even launched.

There's also aquatic animals with wheels, hands-free guns, dog soldiers, and stationary for space. Check out #566 for part 1!
