We give an action of a Lie subalgebra of the Witt algebra on foams. This action is compatible with the \mathfrakglN-foam evaluation formula. In particular, this endows states spaces associated with \mathfrakglN-webs with an \mathfraksl2-action. When working in positive characteristic, this can be used to define a p-DG structure on these state spaces.
