Years ago, in a school that no longer exists, I found two pairs of old safety goggles at the back of a cupboard. My younger son claimed one pair, and we have both used them, on and off, ever since.
More recently, I came across a piece of scrap brass, already drilled with thousands of holes.
After months of reminders from Conker-X
, I eventually brought my goggle bang up to the 1890s...
(This instructable only details my own goggles - Conker will be publishing his own goggles when he gets time.)
