ECA day was officially over and we had a plethora of dry ice remaining. Whimsies - what we call members of the Whimsical Science Club - are resourceful creatures. We improvise wastes, just like how we normally improve ideas. Leaving most of the people behind, we rushed to another block of our college where not many people were at that time. It was the perfect place to use our remaining dry ice.
The stress of A2 had not devoured our proclivity for fun and excitement. Standing at the 3rd floor, we mischievously filled in an empty plastic bottle with hot water. Our hands moved deftly as we rolled the left over flyers (we used them to promote our club) with pieces of the bone chilling soild CO2. One of us - I shall name him A to prevent him from getting into trouble from the college authority - practised closing the bottle with its cover. He was equally scared as excited. A lag of reaction could have devastating impact on him - GG.
B - another friend of mine who would not like to have his ass kicked by our college authority - quickly inserted the cold and freezing rod shaped like that of a wrapped sweet into the plastic bottle. "Shit the the hole is not big enough". Our peaked excitement subsided. "Potong steam". B readjusted the rod size and there, another try. This time, it entered nicely.
A, now with adequate practice, closed the cap as fast as a soldier ready to throw a grenade. We watched as the bottle dropped onto the garden below. The slim bottle bacame plummer,and plummer, until a point where we thought its obesity would cause its demise. " Any moment now. Run! Run!" we moved further from the bottle, though we were already 3 floors away. It was as though the bottle realized its danger and was tight with its diet. Our plan failed. The bottle stopped expanding =(
We whimsies are not only resourceful but also persistent. We are good learners. This time, we altered our variable. We knew that the concentration of dry ice should be increased. So was the water level. But too much water - though this would make the expansion faster - was not favorable as the impact of the bursting of the bottle would not be as great. Too little water on the other hand would result in the requirement of more ice to burst the bottle, in other words it we would get the same result as that of the first experiment. As Mr. Peter told us, we took the optimum level.
A, with fear that 2 rods would require a faster closing of the bottle, practised again. One rod entered. There went another. A quicky closed it, shook the mixture and threw the 'grenade'. This time, it had better work. It expanded and expanded and expanded. Bigger and bigger and bigger. "Oh it's already bigger than the previous bottle!"
Excitement and fear entwined as we watched the breath of the ice God furiously demanded freedom; when its wrath peaked, a deafening roar eclipsed the former and made the latter dominant over all other emotions. " BOOOOOOM!!!!!" It was as loud as thunder, perhaps even louder, causing alarms of cars rang. We ran like cowards.
We tried to act cool to prevent the guards or any passer by from realizing the culprits behind this prank. Rain fell immediately after the explosion and hopefully, people might think it was in fact thunder which caused all the chaos.
We unanimously labelled it as the best Whimsical Science Club activity ever.
