This product, a switch activated measuring cup mounted on a flexible gooseneck mount, from Enabling Devices ($122.95) is my first Device of the Day. I acquired one just this past September, thinking I would use it for cooking lessons.
I have used it for cooking, and so much more. I've used it in science to measure and pour experiment ingredients, in math to teach measuring liquids, in art to drop glitter and sand onto projects and in even in history when we made Silly Putty in a lesson on 1940's inventions. This device is limited only by creativity.
Another bonus (that admittedly I viewed as a drawback at first) is that one switch will pour while a second switch with upright the measuring cup. This design creates teamwork between my students who use switches in handling the measuring and pouring. (You can also just move the switch from one port to another). This nifty device has many uses in the intensive special needs classroom.
