Human: Mentos and Coke Rocket, load the mentos into the top and slide a paper clip into the hole to secure them in place. Place the plug at the bottom and fill the base with coke. Twist the lid onto the bottle and remove the paper clip then run... I've had limited success and experimented with various sealing bands to prevent the mixture from squirting out where it shouldn't!
