It's one of those moments that has to be seen to be believed - and luckily it was caught on video.
Timaru man Samuel Kempf was recently in Europe representing New Zealand in the Fistballing World Championshops in Switzerland last month.
After the championships, Kempf took a holiday and headed to Barcelona, where he visited a theme park and got the best holiday footage: showing him on a rollercoaster, catching a phone flying through the air at 134km/h.
Footage of that moment, uploaded to YouTube by Kempf, has gone viral with more than 160,000 views in the first 24 hours.
