Have you ever wondered "What are the five basic flavours?" "Why is chilli hot?" "Why do we like or dislike certain foods?".
Questacon has all the answers on Sunday at two talks called Tasty Science.
The show looks at how and why your tastebuds experience certain flavours, and even gives visitors a chance to taste things for themselves.
The shows are on at 11am and noon on Sunday.
There are in the Japan Theatre, Main Foyer.
Do yourself a flavour and get along.
