1. A laminate is a material that can be constructed by uniting two or more layers of material together. The process of creating a laminate is lamination, which in common parlance refers to the placing of something between layers of plastic and gluing them with heat and/or pressure, usually with an adhesive. However, in electrical engineering, lamination is a construction technique used to reduce unwanted heating effects due to eddy currents in components, such as the magnetic cores of transformers.

2. Popsicle is the most popular brand of ice pop in the United States and Canada. The first ice pop was created by accident in 1905 when 11-year-old Frank Epperson left a cup of soda on his porch in cold weather overnight. The next morning he went to go get the soda and it was frozen, so he put two sticks in the frozen liquid and pulled it out, and tried it. “Popsicle” is a trademark held by Unilever.

3. Duplo (trademarked as DUPLO) is a product range of the construction toy Lego, designed for children aged 1½ to 5 years old. Duplo bricks are twice the length, height and width of traditional Lego bricks (eight times the size in volume), as a result being easier to handle – as well as being far harder to swallow – by younger children. Despite their size, they are still compatible with traditional Lego bricks. Initially launched in 1969, the Duplo range has gone on to include sets with figures, cars, houses and trains. The most common of all Duplo bricks is the 2×2 brick.

4. A detergent is a surfactant or a mixture of surfactants with “cleaning properties in dilute solutions.” In common usage, “detergent” refers to alkylbenzenesulfonates, a family of compounds that are similar to soap but are less affected by hard water. In most household contexts, the term detergent by itself refers specifically to laundry detergent or dish detergent, as opposed to hand soap or other types of cleaning agents. Detergents are commonly available as powders or concentrated solutions. Detergents work because they are amphiphilic – partly hydrophilic (polar) and partly hydrophobic (non-polar).
