When you pop to the pub for a glass of wine or a pint of beer you probably expect a good chat and a drink.
This week the Pint of Science festival has been in Cardiff for the first time.
The aim is to bring science and technology to a new audience and try to get more people involved.
Watch the report below:
The talks are short - no more than half an hour.
All you need is a seat, an appetite to learn, and - yes - you are allowed a drink.
The team want to highlight the work done in our universities and laboratories.
Pint of Science events are already held worldwide.
The organisers hope its Welsh debut is a good sign that it'll continue to grow.
