Tape that changes color with the touch of your hand WOW! Kids can't get enough of this color changing tape. Place this tape on a wall, table or other clean, smooth surface for visual stimulating fun.
- Size: 1.88" x 10 yards, 48mm x 9.14m - 30 feet of tape
NOTE: color change occurs based on temperature differences. Color of the tape is darkest when cold and color is lightest when warm. Assuming you are using your hand on tape, your hand cannot be warm at the same time your mat is warm. There must be a difference in temperature for the tape to "work" It is not going to "work" at room temperature (low or no ac, or heat on) This will not provide a temperature difference between your hand and the tape.
