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."
