Methinks "cold flow" would be a more applicable mechanism.
<https://www.merriam-webster.com/dictionary/cold%20flow>
That's where Tom leans on his bicycle frame, which then slowly flows
in the desired direction.  How he was able to do this from inside the
frame tubing is left as an exercise for the believers.

There is also SMA (shape memory alloy):
<https://en.wikipedia.org/wiki/Shape-memory_alloy>
which can be deformed when cold but returns to its previous shape when
heated, which Tom does with a breath of hot air.

I really wish that Tom would introduce his amazing technology to the
automobile industry.  My Subaru has numerous dents from trees and
branches falling on it during several years of winter storms.  It
would be really nice if I could just push or heat the dent and have it
return to its original shape.
