Can someone explain me where can I find the generator or baterry for the scientist in level 4?
Use your rain pen and wire pen .... hope that helps
But how do we need to use them
Fill the bucket with your rain pen then use your wire pen to connect the machine to the bucket.
Electricute the bucket by drawing a raincloud above it, then, draw wire from the electricfied bucket to the machine
You use your rain pen to put water in the bucket next to the scientists machine and then using your wire pen connect the bucket to the machine.
