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.
