What Goes Up is the 5th produced episode and the 4th broadcast episode of the first series of Supercar.


After a dangerous canister in earth’s atmosphere fails to explode, it is up to Supercar to destroy it.


At the base in Nevada, a man called Colonel Lewis has asked Mike, Dr Beaker and Professor Popkiss to assist in an American Air Force project. The Project is called “The Fourth of July”, because it involves a large explosion.

The Air Force has a balloon up in the atmosphere carrying a canister full of the Air Force’s new fuel, which is a highly explosive substance.

Because of the substance, it is too dangerous just to bring it back down. The slightest touch on the canister could cause the fuel to explode. So they intend to explode it in the atmosphere.

Dr Beaker has the detonation button on his desk. They begin the count-down.

Ten, nine, eight, seven, six, five, four, three, two, one. Dr Beaker presses the button, however the balloon has not detonated because of a fault.

They decide that the only way to destroy balloon is to send Supercar with a gun mounted on it, up into space where Mike will be able to fire a missile, destroying the balloon.

Before Mike sets off, he must take in some considerations. Since the fuel will cause a very big bang when the missile hits the canister, Mike will have to fire the missile at two thousand miles. There will also be a considerable amount of radiation in the sky, so Mike will have to wear a special suit to deflect the radiation.

He sets off and when he reaches the balloon, he decides to go in even closer so he doesn’t miss. He fires the missile destroying the balloon and still manages not to get caught in the explosion.
