Edit: removed two white surfaces to prevent an alternative method to get the cube.

Thanks your tip in the workshop helped. dropping the cube was the only way I thought it might be done, but it took me at least 10 tries to get it timed right - more than a little frustrating Thanks for creating.

It's much easier if you use the upper row of the white surface to put the cube in position and then create a new funnel portal in the bottom row where the funnel will suck you in and catch the falling cube. That way, it's easier to gauge whether the cube is directly above the button. Thanks for playing.
