Natalie Fee talks about impact the clip (at the end of the previous segment) had on her life and how she started out on her journey. One stop on that journey was a music video.

Natalie provides some facts and figures about how much garbage is getting flushed down the toilet in the UK, and goes on to tell us about a successful campaign she spearheaded, aimed at manufacturers of cotton swabs.

Natalie provides some tips for wasting less plastic and leaves us with a slogan to help us rethink our flushing habits. She involves the audience to bring the message home.

When hit US sitcom That '70s Show finally ended its long and successful run, the actors came together to reminisce and relive the good times and best moments. How did it all get started? Did any of them ever dream that the show would be so popular?

Looking back at the pilot episode from all those years ago, the actors explain why the show made audiences of different ages laugh, and cringe at their own acting skills.

Eric finds that the road to happiness is not without a few bumps as his and Donna's teenage romance becomes an adult relationship.

The cast hadn’t met before filming the show, but there was a good chemistry between them right from the start. When they got together and were having a good time, the viewers knew it, and very soon were also having a good time watching.

Some memorable scenes came when That '70s Show pioneered new camera techniques. They were the first show using “three sixty degree” scenes, bringing each character into sharper focus, often with hilarious results.

The cast recall their favorite moments of a show that didn’t mind pushing the boundaries. A cartoon episode was made, and the “three-sixty” scenes were a huge hit — to the extent that they often weren't even related to the storyline.

The basement film set and its contents have taken a battering over the years of filming. Now that the show is coming to an end, the actors are dividing up the props, keen to take a memento from the studio that has become a home away from home.

The whole cast got to break out of their routine and enjoy roles in the many fantasy sequences that were a feature of the show. Often based on iconic stage and screen performances, some actors were able to live out their personal acting fantasies and play parts they had always dreamed of.

Things on set didn’t always go as planned. Sometimes the young actors got the giggles, and sometimes they even got hurt, but each found their own way of dealing with the unexpected. Luckily, the director of the show was extremely patient with them.
