OHP – a poem about light

OHP
O… H… P…
[Three letters that mean so much to me]
[But only if you’re of a certain age]
[Will you remember they were all the rage!]

The “Overhead Projector” –
A box of light to clarify conjecture.
Whether Geography, Biology, Maths or Art,
This tool was used to light impart
To prepubescent pupils with darkened minds
Seeking knowledge and truth to find.
“Let there be light!” the teacher cried,
“Shut the curtains, it’s too bright outside!”
And flipping the switch, the fan engaged,
Learning leapt to life in this modern, high tech way!
