Henna Tat Pen

While we're on the subject of tattoos.


We have a solid tradition of drawing all over each other with sharpies at parties. (Is that toxic, by the way?)


Problem is, they only last a couple of days.



So, why not something a little more permanent, like henna?




The benefit is that would last a lot longer, like for weeks.


And while you're at it, make it more user-friendly than a paintbrush. You could have it available as a simple pen.


Oh, look, somebody already invented it.


This blog should be entitled "My awesome inventions that someone has already invented."
