Backyard Science Projects

Physics, Family & Fun!

CoasterDad is mostly about roller coasters. But wait! There’s more! The world is full of amazing, exciting backyard science projects we do with our kids, and you can do with yours!

Roller Coaster Stick Bomb! – May 2014

Boy oh boy, this was a fun one! After seeing a stick bomb on YouTube, I just had to make one! We built our stick bomb on The Caution Zone roller coaster in my backyard, and set it off to the delight of neighbors and kids everywhere. The video (above) is yet another CoasterDad YouTube Sensation, which pleases me to no end! Thanks for watching, and please click here to subscribe to my YouTube Channel! You’ll be glad you did :) Every month, we give away a Free CoasterDad T-Shirt to one of our new subscribers. What fun!

The Caution Zone – November 2013


Our first Backyard Roller Coaster was built in our back yard. Why? Because Lyle thought it would be a good idea, and a lot of fun. It’s not the first time one of Lyle’s Ideas got big, and then bigger!

    I wish I could participate in this competition, but I live in Denmark :/ i am an autist and live in a place with other people like me. It would be so awesome if we had our own roller coaster in the back yard. It would make being socially easier

    the next coaster you build you should make a chain lift with a full anti-roll back system! I really hope to see this on your next coaster!

    Awesome ride! I’d like to see what you were using to allow the wheels to pivot left to right and up and down for this car and the crossbow car. I built a backyard coaster about a year and a half ago and ran into a problem with front and back wheel assemblies wanting to shimmy on the turns creating friction and slowing the car down. Ended up making the wheel assemblies stationary and that seemed to correct the problem.
