Check out this video below of an RC clown fish and shark (Air Swimmers) flying around scaring people as they go. Each Air Swimmer is 57 x 36-inches long, powered by only four AAA batteries and has a range of up to 40 feet. Simply fill it up with Helium at any party store and your ready to go!
Air Swimmers are ready for purchase on their website below!
Pretty awesome idea... wish I had one :)
Thanks for the news tip Mariano
