When using standard thermodynamic values, the chemical reaction whereby ATP is converted to ADP is found to have a positive value for ΔG. This would imply the reaction REQUIRES energy. However, analyzing the process under physiological conditions shows that ΔG is in fact negative, as expected.
What happens when chemistry and illusion collide? In The Disappearing Rainbow, a simple acid–base demonstration transforms into a spellbinding performance. With a single pour, colorless liquids bloom into a vibrant rainbow—then vanish in an instant. Now, with the arrival of the “Assassin’s water bottle,” this classic demo gets a modern twist that makes the magic easier (and cleaner) than ever.
