A bullwhip breaks the sound barrier every time it cracks. The "crack!" is actually a sonic boom.
We are so proud to have been chosen to supply the Kangaroo bullwhip used in season 5 of the biggest television show in the World. The character in the show (Nymeria) uses a slightly adapted version of our Kangaroo bullwhip and as you can see from the interview below a lot of what you see on screen is the actress using the bullwhip not CGI.
Twenty-two year old actress Jessica Henwick, who describes herself as "Singaporean-Brit," portrays Nymeria Sand, one of Oberyn Martell's eight daughters known as the "Sand Snakes." The result is that Henwick's character is the first prominent East Asian actor to play a prominent speaking role in the TV series.
In an interview with the Huffington Post's Macrina Cooper-White, Henwick talked about training to use the whip.
"Nymeria is the most strategic of the three sisters and I think her whip is very representative of her character. It's not about brute force with a whip... it's about balance and timing, precision and accuracy — and all those things are very much Nymeria...
Nymeria’s weapon is a 8ft-long bullwhip. I’ve been clarifying the length because people are like, “Ohh, like a Fifty Shades Of Grey whip?” and I’m like, “No, like an Indiana Jones whip!” Inmost fight scenes the characters use rubber weapons, but the bullwhip is real – the crack it makes sounds like a gunshot. It was so loud I had to go down to my parents’ house in the country to practise.’

"I had six months between my first session and us actually getting round to filming the fight scene. I worked with Paul Shapcott, who is from New Zealand and worked on the Hobbit films. He knew the bullwhip and he taught me how to hit targets. At one point he was throwing toilet rolls into the air and I was having to hit them out of the air....Other times he would put sticks in various positions around our rehearsal room and I’d have to go and wrap my whip around them, and then for the last one I'd have to lock it in place so I could actually pull the stick away. It’s like learning to ride a bike — once you know it, you can always go back to it. It's just about feeling the balance and the weight of it... Yeah! They made a proper whip for me that has a bronze handle. It's made from kangaroo skin, it’s 8ft-long and it’s really heavy. That’s the one I had to use for close-ups. Then for the majority of the fights, I used one that looked identical but the handle was rubber and plastic, rather than bronze. It was a lot easier for me; it didn't throw me off balance.
And then they did have a standby whip, the third whip, which was just a handle. They said, 'This is in case it gets too dangerous,' but actually I never really worked with that one. The whole time I said, 'I've learnt it, I've learnt how to do it. Can I do it?' And they kept saying, 'No you're gonna have to use the safety whip.' But every time we got to set, I would use the real whip."
"I think the quality of the Kangaroo whip is a 10! its kick ass !" I love it".
"My husband loves his kangaroo whip. He even used it as a prop in a family photo with our grandson. He is very proud of his whip and the story of how it got here".
"A quick thank you it arrived today Nigel is very pleased with his Kangaroo whip he says it is very light. A gentle flick across the room and it moves like a snake! It took a real effort of will not to take it to work (the gym he holds his class) for a good crack. Well worth the wait :-) he is going to enjoy breaking it in thanks again."
"Thank you for the Bullwhip -it was a present for a friend - a frustrated cowboy - he goes to America and Canada each year to ride remote trails - horseback of course. Excellent job very pleased with it - he was cracked up. (sorry). Grateful thanks".
