Beakman explains what acids are and performs a demo where he puts bone in vinegar for a few days to show that they become rubbery. He uses an animated clip to explain that acids take things apart rather than actually "burn."
Beakman explains that there are chemicals all around you at home. He explains indicators and creates a DIY indicator out of red cabbage juice. He gives examples of common acids and bases found in the home in order of pH and uses the red cabbage to show their differences.
Phil demonstrates the relationship between acids and bases using small balls that symbolize protons. He explains that not much happens when they're together but that introducing a solvent, such as water, causes a reaction.
Hank explains that DNA stores our genetic instructions and illustrates how DNA is structured. He explains the parts of the Double Helix structure and uses a book to put into perspective just how many base pairs are tightly packed in each chromosome.
