Time to take a break from forecasting the future of advertising.
Totally unrelated.
How to build a really big snow wheel.
Start by making a regular snowball. This will be the seed, or nucleus around which the snow wheel will form. Make it as large as possile, as long as it's round. Larger is heavier. Be realistic. Now, drive an eight foot long, four-inch diameter PVC pipe through the center. This is your axel. Put a rope through the axel. More on why later.
Put one person on each side of the axel (only one- they need to be able to move aside if the wheel falls) and two or three people behind the snowball. Start rolling in onl
y one axis. The snow wheel's width will never get to be much more than the diameter of the original nucleus. Go downhill if you can. If flat ground (an athletic field, for instance) is all that's available, be prepared for a workout.
As you proceed, you will inevitably find that the wheel gets lopsided. Periodically stop and reshape for roundness. As perfect as possile. Attach a short rope to the axel and use it to measure the radius. Carve with long knives, spatulas. Patch the gaps. Keeping it round will make all the difference later on. Don't let it get lopsided side-to-side either. It will fall over and kill someone. Or break their legs. Or kill them.
Once it gets too heavy to push, harness up as many more worker ants as you need using the rope running through the axel. Be creative!
Long after the snow on the ground has melted, you'll have a monument to your snow-based engineering skills.
