Update

Ok, its been decided. The group will be coming over to my house to do the experiment tommorow. Yong xian will be getting the sand as i already gave him a dollar to buy a bottle of water. If you are a good samaritian, you would pay me 20 cents tommorow. Results and video (not confirmed) will be posted on tommorow. One more thing, we will also be finishing all the weekly worksheets that requires the whole team as well. Otherwise, good luck for your exams and good night!
