Nasa's foremost rocket scientist, Marc Millis, has admitted he still doesn't know how to use a toaster correctly.
"I tried it on 3 but the 'toast' just came out looking like dirty bread. When I upped it a level to 4 it took the fire department an hour to put out the flames."
Mr Millis now furtively hangs around the launch pad with a bit of bread on a stick waiting for blast off.
