Yes, it is possible to disconnect smoke detector wires even if it is hard-wired into your home's electrical system. A hard-wired smoke detector in the home extracts power from an electrical switchboard. On the other hand, a battery-operated smoke alarm does not have any exterior wiring. Flip the electrical switch that modulates the smoke identifier. On the off chance that there is no labeling on the board that assigns a switch for the finder, toss the fundamental breaker to the Off position. Make sure that there is no power supply to the smoke alarm by the means of a noncontact circuit tester. Assess the alarm wires. Contingent on the kind of smoke alarm installed in your home, the wires will either be linked with a plug and socket or with screws. Then release the plug from the socket using a screwdriver to disengage the alarm.
I had a set as a child that used two thin 'rails' of narrow rubber tube, about the size of air tubes for fish tanks, to support a marble. Air tube is cheap / light / flexible, too. You can use dowels to support it into the main shapes, and glue toothpicks every inch or two along the track's length to maintain the spacing. -Edit- Tried to add a link before, but couldn't post. The product I had as a child was called 'Spacewarp' by Bandai or Blackwolf
