We would like to express our greatest appreciation to the School of Science and Technology, Singapore for allowing us to embark on this exciting project in the field of Chemistry and Physics so that we could express all our interest in the area of Science.

We would also like to give our heartfelt thanks and gratitude to our mentor, Mr Tan Hoe Teck for lending us his special alkaline battery charger, and guiding us throughout the project when we had any doubts. We would also like to express our special gratitude to our teacher, Mr Teng Juin Yan, for helping us along the way, providing us with any needed assistance, and helping us to ensure no one tampered with our experimental set-up after it was tampered twice.

Finally, we would like to thank the lab staff, for bearing with the noise generated by the motors, part of our experimental set-up, the whole day, taking care of our set-up, and providing us with the items that we needed for our experiment.
