Tim invites his friend Gerard Darby back to the studio, so Gerard can show Tim some of the items from his collection. This time, the theme is all related to unusual glasses and bottles.

A pop up wine glass, maybe useful for picnics? A 'tipsy glass' that leans to one side. And a 'civilised glass' once you fill it above a certain point, the built in siphon will empty the contents from a hole in the bottom. Like the Greedy Cup which is normally made from pottery, these drinking vessels suggest that we should not be too greedy!

A bottle inside a glass, and a glass inside a bottle. This one will need a long straw!

The next glass has lines and letters on the side. Fill the glass up to the line that says 'A' next to it, and when you gently hit the glass, the note that you hear is an A!

Finally, a champagne glass that has been made inside a glass tube. More clever glass blowing!
