100 Days of Science #99-- Rocket Science

We set off our model rocket.  Alec got this kit one year for his birthday and I never really read the box.  I assumed it was like our other model rocket kits and we needed to buy a fuel pack for it.  Turns out it is a simple baking soda and vinegar powered rocket.

While we have used baking soda and vinegar for what seems like a million other experiments the boys were still eager to set off the rocket and see how high it went.

 We ended up setting it off three times.  The first time I filled up the baking soda and vinegar chambers but I didn't press the rocket firmly enough into place and it shot off before I had even turned around and it didn't go very high.

There are holes all up the sides where you pour in the baking soda and I was surprised at how much baking soda falls out of them.. luckily it didn't see to impact the experiment.

Alec set if off next and his rocket went so far so fast I could not track it with my camera!  It looked like a dot in the sky.

I encouraged Evan to give it a try too and made sure to stand back far enough that I got a great shot of the rocket and it's baking soda trail.

We talked about the differences in each "flight" and realized that Alec's flew so much higher because he was better about pushing the rocket way down onto the launch base making a better seal for all the pressure to build up with.

It was a lot of fun.

  1. Oh my gosh, this is an awesome experiment. I am tucking this idea into my back pocket and maybe looking to purchase it for my daughter for her birthday or at Christmas. She would love it!


    1. Thanks! We were so surprised at how far it went.

  2. That looks so cool! I think my husband would like that experiment LOL! xo, Biana -BlovedBoston
