-##  Aside on Wet Gates
-
-If you've already encountered [wet gates](/guides/core/hoon-school/R-metals) and how they handle their sample, you may eventually circle back around to attempting to write statements which curry a wet gate.  For instance, here is an attempt to curry `++reel` which itself takes a gate (in this case `++add`) as an argument:

For instance, here we curry `++reel` which itself takes a gate (in this case `++add`) as an argument:
 
 ```hoon
 > ((curr reel add) `(list @)`[1 2 3 4 ~])
-mull-grow
--find.i.a
-dojo: hoon expression failed
+10
 ```
 
-Unfortunately, `++cury` and `++curr` don't work with wet gates, and you'll see a `mull-grow` error.
-
-One solution is to “dry out” the wet gate using [`++bake`](/reference/hoon/stdlib/2b#bake):
+### Exercise:  Calculate a Factorial
 
-```hoon
-> ((curr (bake reel ,[(list @) _add]) add) `(list @)`[1 2 3 4 ~])
