Starlight and Intumescent Materials

The video explores the history and mystery of Starlight, a heat-resistant material invented by Morris Ward. It discusses Ward's secrecy and the challenges he faced in commercializing Starlight. The video also demonstrates a homemade version using common ingredients and explores the concept of intumescent materials, including commercial intumescent paints. The video concludes with a discussion on additional insulating ingredients and a sponsor message.

Who invented Starlight, the heat-resistant material?

• Morris Ward

• Nikola Tesla

• Albert Einstein

• Thomas Edison

What was the primary purpose of Morris Ward's public demonstrations of Starlight?

• To test its limits

• To gain publicity

• To patent the material

• To sell the formula

Which household ingredients did the narrator use to replicate Starlight?

• Cornstarch, sugar, and borax

• Baking soda, cornstarch, and white PVA glue

• Flour, sugar, and water

• Salt, vinegar, and baking powder

What was the main issue with the narrator's original formula once it dried completely?

• It became too sticky

• It lost elasticity

• It was too expensive

• It became flammable

What additional property did borax add to the improved formula?

• Higher flammability

• Better color

• Increased stickiness

• Mold and insect resistance

Why did Morris Ward refuse to patent Starlight?

• He didn't know how to file a patent

• He wanted to keep the formula a secret

• He thought patents were too expensive

• He didn't believe in patents

What was one of the reasons Starlight never made it to the market?

• It was patented by someone else

• It was not effective
