This week we are making cars out of recyclable materials such as used bottle caps and so on. The members are divided into 5-6 groups. They are expected to complete their cars, which are powered by balloons, by race day which is next week. Some groups looks promising to succeed, however some groups are just playing around. Which ever way, I'm sure they all had some fun at the end of the day. A group even tried to do something extraordinary. Instead of using air as people would, they are trying a method which uses water to propel their car forward. Pictures and 2 videos is provided below:
Although the liquid propellant used in the above video was water instead of air, it still moved remarkably fast. Hmm...an idea for another science project perhaps?
The car in the above video did some impressive drifting but moved only about 45 cm. Hope they can do better on race day!
