The next challenge was to make a substance called Oobleck out of cornflour, water and food colouring.
And we also had to make a lander that would land on the Oobleck without making a dent.
There was another challenge like the Lunar lander, but it had marshmallows in it instead of eggs and you couldn't let the marshmallows out of the lander.
The last one was to create a monster out of pipe-cleaners, straws and balloons.
