Laser 'tattoos' for labelling fruit

arielCo (995647) writes "Those helpful-yet-annoying little stickers on fruits that tell the cashier the variety and brand may be replaced with a CO2 laser etching. Quoth the PhysOrg article: "the laser cauterizes the peel, much like when a laser is used on human skin. The cauterized area is impenetrable to pathogens and decay organisms and resists water loss". Demonstrated on a grapefruit, it is due for testing on "tomatoes, avocado and other citrus fruits". The original paper (abstract) requires a paid subscription."

Produce as Accessories (1)

Yippeee! Tattooed produce! Now I can have my fruits and veggies match my ink! And the bowl of apples on the diningroom table can match the pattern of the tablecloth! I'm so excited!!!

Don't get your hopes too high for now - "tattooed" is a bit of a misnomer, since there's no ink involved. Though, keeping up the Body Modding analogies, it's more akin to branding =)

"I am not a number! I am a free fruit!" (But you'll have to pay for me anyway...)
