Montreal artist Cesar Saez is creating a 300 meter banana, with a bamboo skeleton and helium bladders, which he intends to launch into geostationary orbit over Texas. It is launching from Baja, Mexico. It will appear in the sky 10-20% the size of the moon.

Just to be clear, 300 meters is over twice as long as an American football field, and 30 meters longer than the Titanic.
