These stunning acrobatic twins are taking social media by storm with 1.8 million YouTube subscribers.
Teagan and Samantha Rybka, 22, share their incredible talent of flexibility and rigorous six hour-a-day training regime online.
The bendy duo, from Perth, Australia, started acrobatics at the age of three with the help of their mum, also an acrobat.
Samantha spoke about the formative years that started the girls on their journey to prime time Saturday night television, after they appeared on Season 7 of Simon Cowell's Australia's Got Talent.
She said: "We have been doing acrobatics since we were three years old and dancing since the age of six.
"Neither of us were born naturally flexible in the back or legs, but our mum inspired us as she was an amazing acrobat when she was younger.
"She shared her passion with us and taught us loads of acro tricks at home. With her help, that of our teachers and our own determination to get better we both worked slowly and gradually on our flexibility and technique everyday through the years.
"We have constantly use each other as healthy competition, if one got a new trick, the other one would keep practicing over and over until they got it too, we always wanted to do the exact same tricks!"
Samantha described the reaction they get to what they do before passing on her advice to anyone looking to take up something similar.
She said: "Most of the time people are pretty freaked out at what we do, especially if we do something really bendy.
"If we are taking a photo or filming a stunt in public lots of people stop to watch and start taking pictures too.
"We perform in big shows, corporate events, parties and weddings as well as performing to the world by posting weekly videos to our YouTube channel.
"We couldn't be more amazed or appreciative of every single one of our subscribers, we are so thankful and absolutely love to know that what we are doing is making people smile and be happy."
Now she's encouraging others who are looking to take up the sport to be safe.
Samantha explained: "I'd advise anyone looking to take up acrobatics to train safe. Slowly and gradually listen to your body and don't give up, keep going and believe in yourself!
"Remember that nothing is a failure if you are willing to give it a go and give it your best shot in the first place. Every fail or mistake is a learning curve and chance to reflect about what you need to change or do to improve.
"If you have discipline, drive and determination nothing is impossible, and the possibilities are endless."
