yes, you heard that right, you can make your own rocket!

break two fizzy vitamin tablets in half
drop them into the bottle,
quickly screw lid back on firmly
give bottle a quick shake shake
and place upside down in glass or jar
stand back and wait
allow at least 2 minutes before the rocket launched
What is the science behind why these rockets take flight?
Inside a tablet of fizzy vitamin are the ingredients of citric acid and sodium bicarbonate.
When a tablet of the medicine is dropped in water, the chemicals react to produce carbon dioxide gas. The pressure builds and… blast off!
