Why does the bottle fall through the table? both CANCOLLIDES are true!

both can collides are true

ply = game.Players.LocalPlayer
mouse = ply:GetMouse()
rise = false
part = game.Workspace.WBM.Union
secs = 0.3
win = false
fall = false

--NEED TO EDIT PROPERTY OF PART2 TO MAKE IT HAVE NO EFFECT ON BOTTLE

--creates function
function Up()
    part.CFrame = part.CFrame + Vector3.new(0,secs,0)
end







--leftROTATON

function Leftmove()
    part.CFrame = part.CFrame * CFrame.Angles(0.1,0,0)
end

function LeftDown()--need to have this to mantain anchor, but have down motion
    part.CFrame = part.CFrame - Vector3.new(0,0.5,0) --speed of decsent 
end







--RightRotation



--creates loop
while true do
mouse.Button1Down:connect(function() --- something stops, the verification??
    rise = true
    part.Anchored = true 
end)

mouse.Button1Up:connect(function()
    rise = false
    fall = true
    part.Anchored = true
end)

if rise == true then--up motion
    Up()
    Leftmove()
else if fall == true then 
    LeftDown()--down motion
    Leftmove()

end

game.Workspace.WBM.Union.Touched:connect(function(hit) --reset
    local find = hit.Parent:FindFirstChild("toptable")
    if find ~= nil then
        rise = false --problem?
        fall = false
        part.CFrame = CFrame.Angles(0, 0, 0)
        part.CFrame = CFrame.new(12.37, 2.98, -19.72)
        win = false
        wait(0.01)
    else 
        win = true
    end
end) --- need to use variable, left from movement script somehow
----change in rotation, due to reset
wait(0.01)
end--AFTER RESET SOMETHING HAPPENS,  THEREFORE RESET AFFECTS OTHER THINGS, Need to reset rotation
wait()
end

Anyone see anything that would cause the bottle to fall through the table?
