This week's puzzle. Why does anyone need an egg timer on the end of several feet of string?
And they need one enoug to groove the bit of wood, attach the timer properly and fit a loop to tie the string to.
More to the point, it's such a popular requirement that someone made a commerical version in metal.
Why?
Did it belong to a schoolteacher? I'm thinking a classroom experiment to show how a pendulum can be used to measure time.
ReplyDeleteAn engineer - but there's no reason it couldn't have been made for one of his kids school projects. Doesn't explain the ready made version however, unless there is a need to do this for more than an educational reason. Hmmm.
