There were pools of Marsdust, fascinating stuff, fine enough to behave like viscous oil, and knee deep.

The oil, thick, viscous, was pouring slowly on to the overheated bearing.

It contained a thick, viscous oil, taken from the frogs who lived in and near the oasis.

The vessel is designed to recover the lightest to the most viscous oil at the rate of 300 tons per hour.

Even the splash of blood was slowed, like a viscous oil falling through water as it sprayed away.

Maybe stirring lightly and having floating lid or a layer of viscous oil on top would pin that down.

He oozed up the overhanging rock like slightly viscous oil.

The key to the $35 million project was the construction of a reversible pipeline which could move the viscous heavy oil into the marketplace.

This technology only works with quartz movements as a mechanical movement does not work properly in the viscous oil.

Carefully he unstoppered and poured a viscous dark oil that gave off a strong, sharp odour.
