A Super-Material You Can Make In Your Kitchen (Starlite?)

I'm glad you were able to do some tests of your own, very helpful results. I may do a follow up soon with an improved version and more history, but what you have done is the result I hoped for from my video: that viewers would expand and improve on my own experiments. As I have many projects in the works all the time I never get a chance to focus on one for as long as I would like to.

2020-05-04 20:33:10 +0000 UTCI was disappointed to see you never followed up on this. This video is what got me here! I have a bunch of questions, but rather than asking you to test it out I did some tests myself. In Summary: You can substitute glue made from flour and sugar for PVA glue. You can substitute flour for corn starch. In the flour version you can substitute water for glue. All the additional samples I tried (dried them all first) were less solid than the original. The flour versions seemed pretty usable and had the difference of being sticky. The version with corn starch and flour glue was the most crumbly and least likely to hold up. Drying it more slowly could help. I did some envelope math and determined that at 1/4" thickness these samples are [edit for bad math:] within the same price per square foot range as ceramic fiber blankets (about $1.00 sq.ft. @ 1/4") Starlite coming it at about $10/sq.ft. The glue is the expensive part. flour, baking powder, and water version at about $1.00 sq.ft. My napkin math is always suspect. I don't have ceramic blanket to test with so I can't say how 1/4" compares.

2019-07-24 20:27:04 +0000 UTCVery insightful. And how good of you to share. How again like an engineer! Years back I encountered another creative engineer, and thought about how engineers invent solutions. The poem to him then quite applies to you you now. imagineering first one must see, must imagine, what is needed, what will solve, what will work, what might be. air is the hiding place of discovery. only then in the mind's eye. will wave equations form. only then will misty shape appear. water is the flowing of our knowing. then will hands build, while chaos resists order, and patience finds its limit. fire is the illuminator and refiner. so a new thing comes to be, a new purpose is known, a new name is given. earth is our refound home. elias http://1journey.net/1journey/Work/imagineering.htm
