Today GB and I decided to try the alka-selzer rocket again. But this time we wanted it to be bigger. So we used a water bottle that has the pull top on it. That way, when the gas needs a quick exit from the bottle, it will be able to escape without exploding.
We tried a couple more times, and got better results with the angle of the rocket. But we didn’t get good video. So this was the one we decided to use. You get the picture, though.
And no, no dogs were injured in the making of this video. Sometimes that dog is such a ding-a-ling………..LOL!

You guys do the coolest experiments. We don’t have any fireworks for tomorrow and thinking we may substitute this rocket launch

That is VERY cool. Glad the dog got away unscathed.

How neat! OK. We ARE going to try this one. And, I’m glad your dog got out of the way! I’ll have to remember to watch our dog, too.

I’m totally buying Alka Seltzer at the store tomorrow. We’ve done this with film canisters (remember those??), but the bottle is a cool alternative.
