15x15x15 8 Equal and opposite - crossbow car

The best way to describe this car is as a crossbow in reverse. When you fire the bolt (the lead weight) it stays where it is and the crossbow (the car) flies across the room. In truth the bolt does move, but the distance it travels is tiny compared to the distance travelled by the car. Mohammed Dalaf commented that he had a project where the car needed to be 15cm by 15cm by 15cm and that inspired me to see what I could make that fitted that specification. This is my eighth attempt. I cast a weight from molten lead. This needs supervision as there are many dangers involved. After I made this video I modified it without the 15x15x15 restrictions and it worked better /watch/YGqLlF9mX46mL Main components are - Plastic tray DVD player feet for wheels 2 discs cut from credit cards for wheels 2 Barbecue skewers Lead weight Flower cane Rubber bands Main tools - Sharp knife Hot glue gun Drill Related playlists 15x15x15 playlist /playlist/PLA5a2xPRSrB3ZFC8DWgONL1RLF61VZZj3 Bargain Store Projects playlist /playlist/PLA5a2xPRSrB0ZqYUdxXaQaJdg-cs3dKIi Crawlerbot playlist /playlist/PLA5a2xPRSrB0ypbT8Tr-CZfXPIiaOHUlL Toy cars playlist /playlist/PLA5a2xPRSrB3lGxxzEo_ZDnjnOtIlk50Q Aircraft playlist /playlist/PLA5a2xPRSrB0nZItxE_78EJP0F99Ghaki Toy Boats playlist /playlist/PLA5a2xPRSrB24vUS9E8zkSgjZysEL00zr Balloon Power playlist /playlist/PLA5a2xPRSrB2Vx0gKEqY4p9JBgqZqrHsr Gravity Powered Car playlist /playlist/PLA5a2xPRSrB1zzCqDckAnlOzz8iViuM94 Other toys playlist /playlist/PLA5a2xPRSrB1SpcRUbQErqNV7E7ulMth- Rubber Band Power playlist /playlist/PLA5a2xPRSrB1otXh0w36OwsYIHZznUWp6 Help Files playlist /playlist/PLA5a2xPRSrB2v0vxMJyZ9cPweAGx1FK6e My Channel page /user/GrandadIsAnOldMan Oldest videos /user/GrandadIsAnOldMan/videos?flow=grid&view=0&sort=da Most Popular /user/GrandadIsAnOldMan/videos?sort=p&flow=grid&view=0 Newest videos /user/GrandadIsAnOldMan/videos?sort=dd&view=0&flow=grid Playlists /user/GrandadIsAnOldMan/playlists?flow=grid&view=1 I have thousands of videos on YouTube, to find one try my search guides /watch/wgcHOoOSBecSH or /watch/kRYwkwgU4jZUw My "GrandadsOtherChannel" channel is generally where I will host the videos that give extra detail or longer versions of the videos I post on my main channel /channel/UC2mp_L8RoxMyw3ewwSecZ6Q Facebook https://www.facebook.com/grandadisanoldman/ Merchandise - Check both of these links if you are interested as the prices will vary and the shipping charges will be different. http://www.redbubble.com/people/grandadiaom/portfolio http://grandadisanoldman.cottoncart.com/
