I have a confession. I am addicted to tea.
Well, to some of you, this will be old news, but something that’s happened since the last time I blogged solely about tea is that I started going to uni. On my way to uni, there is a bubble tea store called EasyWay, where I would stop almost every day just to order large sugary teas.
I knew it then and I still know it now.
It’s a waste of money.
Lately I’ve been thinking of a solution to this problem, and have finally come up with something plausible. Every time I pass an EasyWay, I will bar myself from buying it, and when I get home I will get a pack of some other tea at Woolworths for less than $5. I will do this for a week, probably accumulating a few hundred teabags in the process, and then stop. From there, I will bar myself from all EasyWay purchases period. Thus, I will not only have saved money, but I’ll have also satiated my tea addiction when I get home. Further, I will be much healthier, since I drink tea without any additives at home anyway, and my family will also benefit from a larger variety of tea to choose from.
It’s foolproof, I hope.
Progress report when the week is over.
Charles, imagine an elevator with inbuilt air blowers, horizaontally facing each other, inside which will not operate if there is any weight put inside it. If I wanted to move a suitcase, would putting the suitcase between the two air blowers, so that the suitcase stays up in the air due to the friction caused by the air, would that allow the elevator to operate?
Newtons third law.

If you have really strong blowers, I don’t see why it wouldn’t work provided that the force of the air was sufficient enough to hold the case up on both sides and the momentum on either side of the suitcase cancelled out. There might be some theory I’m missing here, like aerodynamics equations or something.
If the elevator is rigid, the horizontal forces from the blowers will indeed cancel out.
Im not sure whether its possible for air to keep the thing afloat though.
Did you do engineering mechanics or some other mechanics/physics course?
No, only Phys 1A.
Maybe you have to consider the lift/drag of the suitcase to keep it floating?
In materials science, engineering mechanics is one of the recommended electives. what’d you do instead of it?
Sustainable energy.
