I'm glad you asked because I just watched a video about all the senses(not just five), so hope this helps. :)
Circus Performers rely on many different senses, but here are the most important ones.
There are way more than five senses and a lot of people don't know that. One of the senses they use is equilibrioception. It may sound very brainy, but it's just a big word for balance. Some tightrope walkers use this.
Another sense they use is touch. This is common. All circus performers use this to perform and make their crowd laugh!
The last sense is Magnetoception. Another big word with small meaning. This word just means they know the direction they're going to perform.
