The more sophisticated jammers only switch on when a signal is detected,
hopefully quickly enough to stop a detonation.

They'll make electronic garage door openers, radio type car alarm tags and
a huge assortment of other things entertaining to use...

I've seen things you people wouldn't believe.
Barbeques on fire by the chalets past the castle headland
I watched the gift shops glitter in the darkness off the Newborough gate
All these moments will be lost in time, like icecream on the beach
Time for tea.
