Is it possible to trigger an event by having two parts touch?

I am trying to make a part that grows and breaks everyone and everything it touches, but Touched seems to only work for people. Here's what I've tried so far, with no luck:

script.Parent.Touched:connect(function(otherpart)
    if otherpart.Name ~= "BasePlate" then
        otherpart:BreakJoints()
        otherpart.Material = "CorrodedMetal"
        otherpart.BrickColor = BrickColor.new(26)
        local o = math.random(1, 20)
        if o == 5 then
            local b = Instance.new("Fire")
            b.Parent = otherpart
        end
    end
end)
