This Swedish waterpark was scheduled to open this summer, but judging by this video it'll be quite some time before anyone hops on one of these rides.

"First we saw smoke," a local resident recalled, "then fire and then it exploded."

Some neighbors have been evacuated, while others have been asked to close their windows to avoid the toxic fumes. It is unknown what caused the explosion, which happened around 10 a.m. local time, but the ride has been reduced to "a skeleton," according to locals.

There are reports that several people were injured, with Sahlgrenska University Hospital confirming it had treated four people for minor injuries without providing more detail …

Rescue services spokesman Klas Lüppert told SVT: 'There is a lot of plastic in the construction. So (the smoke) is not healthy to inhale. That's why we're going out with a public health warning.' An employee of the site, who wished to remain anonymous, told SVT the explosion was so intense that it was felt in adjacent buildings.

I'm glad everyone is okay (or at least it seems so), but I'm still over here trying to figure out how a flippin' waterslide explodes.
