My toddler is obsessed with rockets at the moment, so I decided to use an extra length of dowel to make him a sturdy one.

I'm currently brainstorming the best way to attach the fins, figured I'd see if anyone here had any ideas

Currently, I'm thinking of cutting perpendicular grooves from the bottom that the fins will slot into, with each pair of fins being a solid piece. But keep in mind I haven't made the fins yet, so that's definitely not set in stone.

Modeling after the v-2 because it looks as stereotypical as a rocket can

Also pretty cool to play with: a bottle rocket. Take a regular plastic bottle, turn it upside down. Add fins to make it stand. Attach a manual bicycle pump to the bottleneck. Fill the bottle a little bit with water and pump it up until the pressure releases the bottom seal.

Edit: make sure that the bottom seal can eventually slide off to release the rocket.

My 5min search resulted in this guide on it: https://www.science-sparks.com/making-a-bottle-rocket/
