Save water Printer Friendly Version
The reservoir in your toilet is much too large for the quantity of water needed to flush out the contents after use. Suppose if everybody put a red brick in the bottom of their reservoir how much water that would save!

Silent Glass Containers Printer Friendly Version
Although I'm a true fan of recycling, I hate glass containers. There's one in my back yard, and every time someone throws in a bottle, I can hear it in my entire flat. Even worse, there's a bar on the same block where I live, and every morning they dump last night's bottles into the container, I simply fall out of bed.
I've spoken to the local trash authorities about this problem, but they say they have experimented with silent glass containers in the past, and that it can't be done. I personally believe that these people are idiots: humans can fly people to the moon, they build submarines and try to extinct themselves by releasing complicated radicals into the atmosphere. Building a silent glass container should be much easier.
Reward: Replace the noisy container in my back yard.
