Family Science Fun: a Homemade Bottle Rocket

By  | Last Updated:  

Mike is a HUGE space movie fan. When we were first together, I tolerated it. Now, 11 years later, I am just as much of a fan as he is. We’ve made it a point to get a sitter and enjoy a date night out whenever a new movie is released. It’s a great way for us to spend time together that we both really enjoy.

We recently saw a trailer for the new movie, Interstellar. You guessed it: we’ve booked a babysitter for the evening and made dinner reservations as well as plans to purchase our tickets. This new movie from Director Christopher Nolan (Inception, The Dark Knight Trilogy) promises to be amazing. Here’s why…

With our time on Earth coming to an end, a team of explorers undertakes the most important mission in human history; traveling beyond this galaxy to discover whether mankind has a future among the stars.

Plus, it’s starring Matthew McConaughey, Anne Hathaway, Jessica Chastain, Bill Irwin, Ellen Burstyn and Michael Caine. Who wouldn’t love that line up!

Even though Sam may be too young, at age five, for some of our favorite sci-fi movies, he loves all things space. This weekend, we all headed outside for a little rocket ship science experiment.

Mike and I aren’t too concerned with reading the directions.. so this project took a few… ahem, tries to get right. We eventually figured it out though! Here’s how we created this fun rocket ship project that our whole family loved!

  1. Using electrical tape, we wrapped 4 pencils (could also use popsicle sticks) to act as stabilizer.
  2. Fill a bottle 1/3 full with vinegar.
  3. Put approximately 2 tablespoons of baking soda into the middle of a paper towel, roll it tight and twist the ends.
  4. Drop in the paper towel, then put a cork in the bottom.
  5. Shake gently, then step back and wait for it to take flight!

Note: this bottle rocket flies about 20 feet in the air — so please do this in an area where it won’t hit anyone or anything.

This was a fun project and a great way to get Sam excited about science. I’ll never forget his giggles of delight as the rocket launched {again and again and again!} in our driveway. Mike and I had a wonderful time building this memory with Sam. I look forward to enjoying more space themed projects together soon!


On November 5th Interstellar will be released in 70MM IMAX ®, 70MM FILM and 35MM FILM, and it will be released everywhere November 7th. Be sure to check out Interstellar on Facebook and Twitter as well. You can also download the app on Google PlayiOS and Online. I hope you’re looking forward to this movie as much as Mike and I are!

Stephanie is in love with a boy named Sam. He has taught her that it's okay to jump first and look later, to wear a dirty shirt to the park and to decide that today is a good day to take a nap in your rubber boots. She hangs out here blogging at Spaceships and Laser Beams and at our printable party shop on Etsy.
