Great news: You can continue to puzzle!

The participation period of the ProLOEWE Science Rally has been extended until 13.09.2021. This means that you still have the chance to submit solutions to the 21 LOEWE research centers and win great prizes!

To our young scientists from 10 years and up:

Together we want to build a lemon battery! You can find out how it works in the video on the ProLOEWE website. With just a few items, you can easily build the lemon battery at home and, with a pair of headphones, even listen to how the electricity flows.

As an additional task there is also a lemon battery calculation. Who can solve it?

Rebuild the lemon battery and send us a photo of it - and if you’ve even figured out the additional task, we’d love to see the results of your calculations, too. We will give away three great experimental kits as prizes among all entries! Whoever solves all 21 rally tasks has the chance to win one of the three ProLOEWE main prizes!

So what are you waiting for? Go for the lemons!

We are looking forward to your photos and calculation results and are looking forward to receiving numerous entries!
