Which forces act when you ride in the Slänggungan Wave Swinger (Chain flyer)? Ride and feel!

• Do all swings hang in the same angle during the ride? 
• Is the motion different for an empty swing? (Why / why not?)
• What factors may influence the angle?

On a special physics day, you may be allowed to bring a small mug of water. Hold the with the bottom resting on the beam of the swing. How do you expect the water to move as the ride starts? Describe your observations.
