https://www.youtube.com/watch?v=V9vx2X8nvwI I like the idea of the reaction rocket because it is simple and I can add my own design onto it.
This video shows the maker creating a looping pendulum. I don’t really like this project because it doesn’t have a useful purpose.
https://www.youtube.com/watch?v=WZzEw-er5UI I like this idea the most because the electric train shows the energy transfer from electric energy to kinetic and mechanical energy. It is also very engaging to little kids, and I can add originality in the project when I design the look of the train.

I like the helicone design because it shows kinetic energy transfer and is engaging at the same time.Although if I am designing for little kids, it might not be that engaging since it is not colourful.
