Cut out the semicircle, together cutting through both sides of the bag. You should finish with a disc of plastic that will be the parachute. 7. Draw a face on the bead. 8. Fasten the strings with a knot then thread them through the loop above the spaceman’s head. Tie the bundle with another knot . Your parachute is complete. Get ready to fly! Operation 16cm Fold the parachute together, keeping the strings free underneath it. Hold the folded parachute and the spaceman together in one hand and throw them upwards as hard as you can. As the parachute begins to fall, it should open and float back to the ground. Adjust the number of nuts on the spaceman’s arms 9cm and legs until the parachute floats down gently without swinging from side to side.

Fun facts • Modern parachutes don’t float down to the ground vertically. They are blow-up wings that glide along as they drift downwards. • In 1960 Colonel Joe Kittenger of the US Air Force made the highest parachute jump ever, from 31,333 metres above the Earth • Parachutes are used to slow down fast-moving vehicles, including dragsters and fighter jets. 5 6
