Thanks alot 4 ur reply. the idea is the food would be pre-hidden inside the table; not exactly cooked food like pasta or so...its can be simply some dry stuff like choklates/nuts plate and drink in a thermokettle. So as one claps, the two doors open and the flat plate levetates. The solution you mentioned maybe the one im looking for, but the details maybe not that easy, how to ensure the sizzor lift keeps the table plane not tilted? how the make the two doors open in proper timing with levitation? do they need a seperate motor or a lever can b extended from the sissor lift to open them?
