Table shown in storage mode. Two pieces of cardboard are placed on top of a sheet of paper to protect the carbon paper.
Place pucks and hose connector to the side.

Remove cardboard – underlying paper shown.
The paper covers the carbon paper. Leave in place!

Vertical support post attaches to the back of the table.
Air hose with gray adapter to connect to overhead air supply.

Carefully attach air hose and electrical connectors.
Another view – wire with 'gator connects to "Spark" terminal on Sparky; green wire connects to ground on Sparky (see below).

Air hose connected to overhead supply.
Use an extra clamp to take the strain off of the air hose.

Air valve settings
"Sparky". Spark wire and ground attach to adapter on support post of air table.

Use three wires connected together to get enough length to reach the adapter.
Use these wires (found in the Bewkes 205) so that no bare ends are exposed.

Place pucks on table – don't attach springs yet, or they'll get stretched out!
Note position of second puck; it must sit on the air table during the experiment to complete the circuit.

The springs are connected to the hooks on the puck, and the posts on the air table.
Detail of the puck. The masking tape collar
keeps the springs from getting caught on puck

The table, with springs attached (only during the experiment).
The completed setup.
