A. Battery Enterprise
"Captain Pickard, I think I know how we can get in touch with the Enterprise. All we need is a simple cell or even a battery to power our communicator. I think I saw just what I needed in the Clingon kitchen."
Help Dr Crusher by designing and building a cell or even a battery which will give the highest voltage. You can use the equipment found in the average human kitchen. You need to be quick because Geordie will be here soon to connect it to an ammeter.

"If only I could lift the dilithium crystal up at least 10cm I could

Design and build a device to lift the dilithium crystal at least 10cm using the reaction between sodium hydrogencarbonate and citric acid. The dilithium crystal must stay up once lifted.
