Bisexual

Scientific estimates as to the prevalence of bisexuality have varied from 0.7 to 8 percent.

Cardboard

Cardboard is a generic term for heavy paper-based products. The construction can range from a thick paper known as paperboard to corrugated fiberboard which is made of multiple plies of material. Natural cardboards can range from grey to light brown in color, depending of the specific product; dyes, pigments, printing, and coatings are available.

Post-it Note

In 1968, Dr. Spencer Silver, a scientist at 3M in the United States, attempted to develop a super-strong adhesive. Instead, he accidentally created a “low-tack”, reusable, pressure-sensitive adhesive. For five years, Silver promoted his “solution without a problem” within 3M both informally and through seminars, but failed to gain adherents. In 1974, a colleague who had attended one of his seminars, Art Fry, came up with the idea of using the adhesive to anchor his bookmark in his hymn book.

Although 3M’s patent expired in 1997, “Post-it” and the original notes’ distinctive yellow color remain registered company trademarks, with terms such as “repositionable notes” used for similar offerings manufactured by competitors.

Legal Pads

A “legal pad” does not mean that the paper size on the pad itself is legal-size (8-1/2”W x 14”L), although it can be ordered that way. A Legal Pad just means the paper on the pad has a vertical line drawn down creating a 1-1/4” margin from the left side.
