The Freeze Ray is a weapon that Mr. Medula teaches his students to build in his hero level mad science class. When Will Stronghold is transferred to hero level classes he is instructed to be lab partners with Gwen Grayson and build a Freeze Ray. Since Will is new to the class he is not sure how to properly build a Freeze Ray and accidentally wires the circuits together for a Heat Ray. Gwen steps in and uses her Technopathy to properly constructed the race so Will does not fail the assignment. Mr. Medula then demonstrates the completed Ray by firing at a student who failed the assignment by confusing rays with Beams.
