On Friday 8th December we had to make something that moved without us touching it. We worked in groups of three to four people. The resources we used were cardboard and plastic tubes, pipe cleaners, polystyrene balls, googly eyes, sticky tape, glue and syringes.
We worked together to see which things would work and which wouldn’t.
The main part of the challenge was to use a syringe to push air in a tube up to a ball or a cup.
When we pushed the syringe with our hands the pressure moved the air through the tube and lifted up the ball or cup.
