Lego Zipline

• Basic LEGO bricks

• Parachute cord or string

Put a LEGO minifigure on a base and build up and around him! When you reach the top, you need to leave a space for the parachute cord (string) to slide through.

Set up the zipline. Find places to attach your string:

• door knob to the back of a chair

• stair railing to table leg

• door knob and you can hold the other end

• anywhere you can get a slope for the zipline and secure the string.

• What makes the man travel faster down the zip line?

• Is a steep slope better?

• What happens to the LEGO® man when he gets to the end?

Change some variables:

• make your zipline longer or shorter

• make your zipline slope steeper

• try to figure out a way to slow your Lego man down before the end of the zipline

• speed up the Lego man by increasing the angle of the slope

• slow down or stop the Lego man by evening out the angle of the slope

• return the Lego man by decreasing the angle of the slope

• gravity works to pull the Lego man down the zip line but the angle of the slope can slow gravity

• tension on the cord is needed to maintain travel
