These days 7-Up is does not contain psychoactive substances. However, the guys from the YouTube channel Periodic Videos were curious to know what might happen if you add the chemical element lithium to the modern-day 7-Up recipe.
The outcome is not quite the expected chemical reaction. In order to find an explanation for this, Sir Martyn Poliakoff shows you some of his finest investigative science.
