smashed up digital test?

Pip
Anyone pregnant or not pregnant ever smashed up a digital? 
I've had a positive on a clear clue. Took a digital and it said "not pregnant" a girl on a moms group said this happened to her friend and she smashed the test up and the strip had two lines, like mine, but the second line wasn't strong enough, so she didn't get a positive on a digital until a week later. 
When I took the digital I downed a bottle of coke and took it with a dribble of wee so don't think I waiting long enough. Just wondering if anyone smashed it to see the inside?
