Linseal is spread over the inside of a tyre tread area as the wheel revolves, ready to seal puncture after puncture. When the puncture occurs, the escaping air pressure forces Linseal into the hole immediately forming a strong airtight seal.inseal is the revolutionary liquid puncture preventative. Linseal is designed to remain fluid inside a pneumatic tyre or innertube. Linseal will seal a hole in the tread area of a tyre instantaneously when applied BEFORE a puncture occurs.
Short Definition: Trypophobia is the fear of groups of holes. It can also involve fears of various patterns.
The evolutionary psychologists I emailed were unwilling to speculate on the potential biological underpinnings for a fear of small, clustered holes. Trypophobia is not an official phobia recognized in scientific literature.
