  The Galileon model is a ghost free scalar effective field theory containing
higher derivative terms that are protected by the Galileon symmetry. The
presence of a Vainshtein screening mechanism allows the scalar field to couple
to matter without mediating unacceptably large fifth forces in the solar
system. We describe how laboratory measurements of the Casimir effect and
possible deviations from Newtonian gravity can be used to search for Galileon
scalar fields. Current experimental measurements are used to bound a previously
unconstrained combination of Galileon parameters.
