Device developed to detect vegetable consumption
There is now a laser that can be used to scan the palms of children to determine if they’ve eaten their vegetables.
“Have you eaten your vegetables? Don’t make me get the laser.”
The device is able to detect the skin decolouration that is caused by the accumulation of carotenoids in the blood as a result of vegetable ingestion.
Alternatively, a cheaper option would be for parents to pay attention to what their kids are eating. Maybe they should instead develop a device that detects bad parenting!
