Wind Racer

Aim: To make the most efficient wind racer which would either go the furthest or looks the most creative. 

Method: 

• Gather all your equipment
• Set up your trolley and your bamboo stick, by placing the stick in the hole. 
• Cut a plastic bag into a partially large rectangle a size that would suit the stick. 
• Repeat with newspaper or paper. 
• Tape your first rectangle to the rod.
• Repeat with your other material. 
• After use sticks to create a structure for the sail, we used skewers but you can use another material. - Since we used a whole newspaper page, we stuck 2 skewers together from the ends. Making it longer. 
• Stick one pair at the top and another one at the bottom
• Depending on the size of your sail and rod place one or two pairs in the middle too. 
• After, make sure everything is secure by using tape in places that are weak. 
• Finally, decorate to make the appearance look more appealing. 

Equipment: Newspaper, plastic bag, tape, trolley, bamboo/metal rod, skewers.

Result: 

Discussion: Pull and friction were acting for the push and stop, but 2 more forces are pushing to each other to not fly the wind racer up or pulled down in the center of the earth. Gravity, and support.

Conclusion: I thought at first the this won't work at all, but when we tried it out is actually pretty cool to do, and it definitely works.
