An impossible souvenir with two wood coffee stirrers. They can even be signed!
Snap off two ends, put them in her hand.
The two initialed pieces impossibly melt into a single seamless "wishbone"...which she can keep forever and ever.
Be a Star at Starbucks...or wherever you hang out for coffee.
Very easy to do
No palming or switches
"WishBone" souvenir is completely examinable: no seams, lines or glue marks...just a single smooth one-of-a-kind impossible object.
