I came across a video on youtube entitled "Palm Beach Steel Drums 46 inch Pan".
The company Reel Ting created this massively big steelpan dubbed the "Terminator". As well it has been submitted the Guiness World Records for being the largest steeldrum.
The record has been held by Jomo Wahtuse
"The largest steelpan is the elliptical "Jomoline" which measures 104 cm (3 ft 4 in) wide and 84 cm (2 ft 9 in) tall. It was created by Jomo Wahtuse (Trinidad and Tobago) and presented and measured in Port of Spain, Trinidad and Tobago on 12 November 2010.
The instrument has 30 segmented chambered notes and has a tonal range from D-5 to G-3. The width of its skirt is 18 cm (7 in)." Guiness World Records
I have never seen anything like this but I do know that I want one. Take a look at the video and let me know what you think. Cheers!
