The area I think was successful is that the catapult is working, it and launch the marble.
The areas I need to improve in the product is choosing a material that is more fit to make to catapult and also using the glue gun more carefully and accurately.
The catapult does not impact on the environment a lot. The potential client will be the people who like to teasing friend using the catapult.

We had a trip to Shimenshan. It’s a really exciting and wonderful trip, we did a lot, such as climbing, rafting and building rafts all by ourselves.
