Use fun machine in real life free energy

This lvl is an example, i built an Automatic Watering Machine. Hi! Principia's fans, i make this contest because maybe programing is not the only thing that can make us famous in Principia, maybe we can make a machine that can gives people inspiration to make it in real life. So please be parcitipate in this contest, your machine may give someone a passion to be an inventor.

Rules : There is no spesific rules, you can use lua but it will be more good if you use non lua things so kids nowadays who dont understand Programming language can make the machines in real life. And it must be a derivative from this level. You have a month to finish it, cuz the contest will end on April first. The most liked level is the winner, so thats why for the people who dont involved, please give your opinion about the machine and if you like it, please hit like. Good Luck Inventor!!
