People like pools for many years. The only problem was that some people couldn't float. People felt safe in their pools, but it was dangerous to swim in lake for fear of drowning. Some people still went to the lake anyway.
One day Dave and Jack were by the lake. They got in an argument and Dave threw Jacks cooler in the lake. When they realized that it floated they threw other things in the lake to if they float. When nothing else floated Jack tried to swim out and collect his cooler. Since he wasn't a strong swimmer he drown in the lake.
Dave immediately went to the store and got another cooler from Wal-Mart. He called his friend Billy. They threw the cooler into their pool and it floated. they took their finding to the people in the community. the people were amazed and wanted to figure out this technology worked.
They sent their idea to china and Three weeks later received a box in the mail. it was the pool floaty. Now people could swim in lakes.
They honor Jack and his sacrifice to the pool floaties every year on December 25th.
