Former W.R. Grace employee: Molecular Sieve Desiccant Beads (also manufactured by W.R.Grace) are even more absorbent than regular silica gel. It's found in most double-pane windows inside the metal track between both panes; slowly absorbing any moisture over many years to keep them from fogging/going 'blind'.
You can use MS to dry flowers in record time... and use it to quickly heat up baby food in a pinch if needed... just put a smaller container of food in a bigger pod filled with MS and pour water of the MS... it's ultra-rapid absorption of water creates heat as a byproduct.
