But when you move, the real magic happens. Houdini disappears, then reappears with a blinding violet flash!
That's right. This is disappearing. Purple. Glitter. Highlighter. Imagine it: from one angle, your highlight is totally invisible... but then you turn your head, and POW! Sparkly purple everywhere!
My emotions right now:
Now you see my glitter highlight, now you don't.
