Star Wars

Of course light sabers were all the rage and I remember having some fairly detailed physics discussions with my uncle about how you could make a beam of light stop after a given length.

That winter I also lucked into finding an old golf bag in the alley.
The plastic tubes that you slide the club handles into were the perfect length and were translucent white. It was a no brainer to masking tape them (my mom wasn't aware of duct tape) to a spare flashlight.

It took a year before a very similar device was marketed to consumers.

I wonder if any of my friends from back then remember that.
