and add a white rod to a double-blue 3D connector.
You may find it easier to take the 3D connector apart to do this.
Next, add this to the top section
and add the top section to complete the tower.
Now build the spinner frame
assemble the counterweight from 5 white connectors pushed onto a blue rod, and secured at each end with a snap cap black
and attach this to the spinner frame.
Now assemble the lower weight from 5 white connectors pushed onto a blue rod, and secured at one end with a snap cap black and at the other end with a purple clip.
Attach one end of the string securely to the purple clip, and attach the other end to a red connector, so that the stretched length of the string is about 40cm /16 inches.
Attach the red connector to the spinner
and fit the spinner onto the top of tower.
Finally, assemble 10 skittles.
Your model is now complete.
To play the skittles game, players take it in turns to hold the weight away from the frame, and swing it around the tower, so as to knock down as many skittles as possible before the weight comes to rest.
You might want to let each player have two or three swings of the weight before the skittles are set up again for the next player.
You can use any scoring system you like, for instance just a single point for each skittle, or a scoring system similar to tenpin bowling.
For younger players, you might want to change the design of the skittles, to make them easier to knock down.
