Edith and Janet Inspect Something

Edith and Janet encountered a strange object during their mid-afternoon walk.

‘What’s that thingamabob?’

‘A battery, silly.’

‘Nah, Edith. Bet it fell out of the sky. Batteries don’t have them blinky things. ’

‘They’re called LEDs. Might be a new generation of rechargeables.’

‘Nobody’s heard of?’

‘It’s a prototype. Someone lost it.’

‘You’ve an answer to everything, doncha?’

Edith turned her attention to Janet.

‘My dear, it isn’t my fault you never finished your education.’

‘Answer me this, then. Why’s the sky blinking along with that LDE?’

‘It’s an LED… Oh dear.’

They disappeared in a beam of pulsing light.
