The Brits are unbelievable

Speaking of TMI (Too Much Information):

Because of all that Global Warming white stuff clobbering England, the
UK Telegraph has contacted a Physics Prof to teach its bewildered
English readers how to make a snowball. According to Professor Peter
Main, Director of Education and Science at the Institute of Physics,
this is how to do it:

Step 1. Check the weather. Outdoor temperatures around 32F (0C) will
ensure the snow has the correct moisture content, a key component of the
perfect snowball. At lower temperatures, the snow may be too powdery,
containing more air and therefore less water, making it harder to pack
tightly into a ball.

Step 2. Wear gloves, not mittens. The individual fingers give gloves a
larger surface area and allow more heat to escape, thereby slightly
melting the snow as it is squeezed into a ball.

Step 3. Scoop up the snow with cupped hands. Typically, fresh,
uncompacted snow is between 90 and 95 per cent trapped air. To reduce
the air content and create a ball, slowly close your hands together
while rotating the trapped snow.

Step 4. Squeeze with increasing pressure: the snow should make muffled
cracking noises as the last of the air is squeezed from between the
snowflakes as they compress. Avoid excessive pressure or your snowball
might disintegrate under the stress. "The trick," says Prof Main, "is to
compress it enough to enable it to stick together, but not enough to
form lumps of ice".

Step 5. Make a small pile of snowballs, ensuring plenty of ammunition in
case of retaliation. Setting snowballs aside will also improve them, as
they recover from the melting caused by your body heat. As your missiles
slowly refreeze, they will become firmer still – deep and crisp and even.

Step 6. Throw first snowball.

If you have done it properly says Professor Main, it won't "disintegrate
mid-flight, but it should splatter on impact without causing damage."

I will issue a pop quiz on this material sometime tomorrow, and for
those who get a passing grade (70% correct), you will be presented with
an official certificate authorizing you to engage in snowball making, so
study hard JOMer's!
