Make your own "Memory Foam"? Answered

Can we make our own "memory foam"?

I'd like to buy "memory foam" in a spray can - but I don't think that product is available.
I was hoping to find something like "tempurpedic" in a spray can.   
I'd like to replicate the really soft top layer as seen in those mattresses.

The "great stuff" foam spray cans come to mind.  However, the end result of those is not a flexible soft foam. Would like to fabricate my own custom foam inserts with the material. 

Any ideas about making or sourcing materials?
Thanks!

I found this “ Memory foam, a viscoelastic material that first appeared on the market in mattresses in 1991, is a mixture of chemical compounds. It is primarily made of polyurethane with combination of other chemicals. The combination of chemicals with polyurethane varies with the manufacturers. The formulation of memory foam has been copyrighted and maintained as a trade secret by the manufacturers. This is due to the fact that different combinations of chemicals with polyurethane deliver different viscoelasticity and density of memory foam. One of the chemicals used with polyurethane is silicone additives.”
It’s probably super easy so they keep it secret. Lol

you can get a mattress topper for like around $120 at walmart. They do shrink though so you need to get a size bigger than your bed.

Just get a bare bed topper memory foam pad and cut that up. I think making memory foam is some industrial chemical/mechanical process not easily done at home. Spray insulation foam cures rigid.
