Acknowledgements

         After several months of research, and experimenting, we are proud of our project and couldn’t have completed it without the help of our parents. We would like to thank our parents for helping us buy the wood, and components for our experiment, and their time and patience in helping us during our experiment and our research .Despite their busy schedules, they still managed to drive us to each other’s homes to work on the project and last but not least for their love and support and always being there for us. Thank you.
