The prompt

Remove the pipe that sticks out below the bottom of the main tube. The bottom of the tube should be flat and open, with no pipe. Then make the whole reactor hollow: keep the inside diameters at 5.08 cm for the main tube and 10.16 cm for the top section, and add a wall thickness of 0.3 cm on the outside. The inside should be one open empty space from the bottom opening to the top. Make the two side pipes hollow too, with 1.4 cm inside diameter, and cut a hole through the reactor wall where each pipe joins, so gas can flow from the pipe into the reactor.
