This has been around for a while and I perform it just like on the video below.
Funny stuff with a cool ending and the kids get it.

Thanks for enjopying the prop George, and the the nice comment!

I've been using mine from the first batch that was made. The box is showing some wear from all the performances over the years. This is a laugh a minute routine, you don't have to be funny to laughs with this one.
Well worth the money and some.
Tricky Ricky

Be using mine tonight in a library show. Very well made prop, loads of laughs, two assistants. I added a bit at end where after the bottom falls out, we need an additional three seconds in the dark. Assistants each hold an end of the tube, and I drape a foulard first over the girl's head, then the boy's, then mine, and finally over the tube. Count out three seconds, pull out rope: knots still there. So whilst they hold the ends of the rope, the audience calls out the one magic word guaranteed to make knots disappear: MOMMIE! Knots are gone and we get baby ropes.

I loved that line when you first told me about it. Glad you enjoy the prop! And the cloth over the head for the magic to work "only in the dark"is a gem also!

Due to this nice post (thanks guys) I have had some inquiries regarding the availibility of the Knot Funny trick.
I am out of stock on them, and am on the road doing my summer fair tour. I won't get home until Sep and plan to build more in October.
You can email me to get on the "interested" list so I can email back when they are again available.
Thanks for the continued support on all of our stuff!
