Schlitterbahn Galveston to open world's largest 'water coaster'

GALVESTON, TX (KTRK) -- Get ready to scream!

Schlitterbahn Waterpark in Galveston is building the world's tallest water coaster.

The attraction will be called "Massiv" and will be open this summer. This is a mockup of what the water coaster will look like:

Water park officials haven't said exactly how tall Massiv will be, but they promise it will be the biggest in the world.

A water coaster is different from a water slide because it uses "water blasters" to propel riders uphill.
