Decisions can sometimes be hard to make, but on this trip to London it was easy to decide on going to Carsten Höller’s “Decision” Exhbition. Arguably, the most fun I have had an exhibition.

Upon entering the Hayward Gallery in London’s Southbank, we were faced with our first decision of the day. Door A or door B?. We choose door A. Pushing the door open, we were immediately plunged into the pitch dark of a metal tunnel. The only way to inch forward was to put one foot in front of the other and feel if the tunnel went up a hill or down, while hugging the wall (and the person in front of you), feeling the edges, which gave away if there was a left or right turn.

Following the light at the end of the tunnel, which felt like ages to get there, we found ourselves in a room full of large flying mushrooms, each pushed around by the public. We definitely felt like we were in some Wonderland experience now.

Carsten Holler, who has been described as the “authentic Willy Wonka of contemporary art”, creates his work to be interactive. He considers his work unfinished if you do not interact.

Next, we find the pill clock where every few seconds one red and white pill drops from the ceiling to a pile on the floor.

 Your decision is to pick it up and take one. Or not. Find out for yourself what happens.

There are rooms with rotating beds guided by lasers, and a ledge to sit on with 3D glasses that take you to an alternate reality whilst you guide yourself through a dark snowy forrest.

There is a huge dice for kids to climb through, and a room of floor to ceiling mirrors to observe everyone that enters.

Once we’d explored all the artwork on the two floors, we stepped outside for the Flying Machines. Strapped into a hang glider and with the speed controlled by one of the staff, you can get the best views of Waterloo below. As a pedestrian entering the Gallery, or simply walking across the bridge, it pays to look up. It’s not something you would see every day – two people strapped into a machine gliding slowly across the rooftop of a gallery.

On the other side of the gallery there is a line where you wait for your upside down goggles. Trying to walk in a straight line to each other to take a photograph wasn’t an easy task. Once we overcame the feeling of dizziness, we tried to experiment more. Hi Five-ing resulted in a fit of laughter.

The final decision you will make on the day is whether to ride the Isometric Slides as part of your exit from the exhibition. Gripping onto the mat and waiting for the green light, we become kids again for a few (very fast) seconds. Best. Exit. Ever.

The entire exhibition is quite thought provoking as you are made to make a decision at every stop. Do you allow yourself to be a guinea pig in the name of art? It allows you to consider your own decision-making process. Do you try something new or not?

There is no decision to be made when thinking of going. Just do it.

The exhibition runs until  Sunday 6 September 2015
