New Challenges

Don't forget if you click on Change Lab, and then click on New Challenges, then click ok. You now have another 103 levels called New Challenges, and you can also go into My Lab and create and save your own experiments/levels.

If your looking for help with the levels in New Challenges, please place the letters N C after the number when writing the subject heading in your thread.
Like "Stuck on Level 21 N C", so that everyone knows your looking for help in New Challenges and not Inventors Workshop (the first 102 levels).
