The “gum” on the ground at Disney is actually sensors for parades. Disney parades have become legendary, a thing of childhood and of nostalgia. The parade occurs every day at 3:00 as staff at Disney will be sure to remind visitors to the park. The parade includes floats and staff dressed up and acting as beloved Disney characters such as Aladdin and the Fairy God Mother.
It is a huge event that requires a lot of upkeep and good management. To technologically organize the event, Disney has sensors on the ground around the parade route called electronic diodes. They look like chewed gum stuck to the ground, but they are actually used to monitor the parade floats.
The diodes communicate to a room underneath Peter Pan’s flight, where workers pay attention to the pace and location of each float. With this information, they are able to inform the float drivers whether to slow or increase their pace to fill gaps in the parade.
A small cubicle near the parade has information including videos and pictures, and it the location from which employees inform the drivers of what pace changes they should make.
