This is The Original Human Cannonball, a High Flying Science Kit from Scientific Explorer.

For over 120 years, daring young men and women have thrilled circus fans with their feats of aerial bravado as they blast out of cannons to soar across the Big Top. Celebrate this glorious tradition by launching your very own Human Cannonball.

A one liter plastic bottle inside a cardboard tube launches a plastic head into the air.
A baking soda and vinegar formula starts a chemical reaction that blasts the Human Cannonball 100 feet into the sky.
A special fueling module adjusts the power to the right level for cannoneers of all ages.
Just pour in baking soda and vinegar, insert the fueling module, and your Cannonball will be ready to fly.
