This document provides instructions for creating a tornado in a bottle using water, glitter, a toy person, liquid soap, and two plastic bottles. The method involves placing the glitter and toy in one bottle with some water, adding soap, capping it with the second bottle, and quickly shaking it to generate a swirling tornado-like vortex inside. The science explanation is that the warm and cool air currents collide and spin due to differences in air pressure and temperature, similar to actual tornado formation.
