Mystery foam flows through Glasgow city centre - so what is it?

AOL Travel

Soapy liquid has been flowing into Glasgow's River Clyde over the weekend - making it look more like a bubble bath than a river.

According to the Mirror, the foam flowing through Glasgow's City Centre was caused by a car wash that poured away a powerful liquid, which travelled down pipes and ended up in the river.

The suds stretched a mile down the river and started frothing towards the river bank.

The BBC reports that the Scottish Environment Protection Agency (Sepa) said it was aware of the problem and is investigating the cause.

Investigators will also want to know if chemicals in the soap have had any environmental effect on the water.

The foam started spewing from an overflow pipe new the Squiggly Bridge and stretched a mile all the way down to the Squinty Bridge.

A source told the Daily Record: "I have never seen anything like it. It is a really thick, slightly pink-tinged foam.

"The most likely explanation is a highly concentrated detergent has got into the drainage system.

"There will be a huge network of inlets to the outlet at the river where the stuff is coming from.

"We haven't had the material analysed yet but it does look like a detergent and there are a few car washes around in that area."

But one nearby car wash worker told the paper: "We use all of our cleaning products. We wouldn't go pouring them away."
