Twiddle Stic: Hello. The name and the picture should be enough to make you laugh. If not, you’re much more mature than I am.

This gadget is meant for professionals. You wrap the hair around the stick, then use a straightening iron to apply heat. The Twiddle Stic somehow absorbs heat to keep the hair cool (and is therefore less damaging) and curls last “until you wash them out.” I’m not sure how this is different from using a regular curling iron, but I’m no professional. The bottom line is, they named a long, shaft-like product a “Twiddle Stic.”
