product description:
Imagine being able to read a thought in a glass of water -- or even your friend’s glass of beer!
CONTACT is an electronic sensor, custom designed by Christopher Taylor for Penguin, that is easily concealed in a card box. The sensor monitors what is in front of it (a glass of liquid, stack of playing cards, or other object) and sends a signal to the performer when the object is touched.
How is it applied Well, with your back turned to a spectator, you recite the months of the year and when she hears the month she was born in, your spectator touches the surface of the water. Now you turn around and read her mind in the water.
You'll instantly know:
• Which shape has been drawn on the water
• Whether a red or black card was picked up
• which object has been chosen
Includes:
• Sensor in card box
• Mini receiver
• Detailed instructional DOWNLOAD including technical details of the system and explanation of routines
• All required batteries
The device is also easily transferable to other containers such as a notebook, drawstring bag, keepsake-box, etc. The sensor-field extends up to 3 inches from the container!
