Review: More Fun Than Anticipated - Super fun and easy! Great value for my money. Perfect activity for age range. Kids felt awesome after installation.
Review: Works well but smaller scale - We have tested this product with both the suggested dirty water and water colored with food coloring and it worked on both cases. It should be noted however that the filtering materials are vert small quantities, so using a big amount of water dirt or colors will make it less efficient faster. I would suggest to do the test with small amounts, I think 50 ml is more the enough to demonstrate the principle. For the dyed water I ended up using only 20 ml. My daughter used it for her science project and it was very fun for her to do and she assemble it herself with my guidance to explain the instructions. She is first grade so I do not think it is very challenging bu fun and educating to observe. I added a video of the assembly and the final product and function. I would suggest to use a heavy glass container as a collector as they suggested because it was too flimsy when my daughter used a plastic cup and needed to add a support cup as seen in the end of the video.

## Questions & Answers

**Q: What kind of functions develop this robot? What does it do?**
A: It goes forward.  That is it.   It took my son and I about 10 minutes to build it, and it ran for about 30 minutes before the battery need to be cleaned, and rebuilt.

**Q: How many watts is the LED lightbulb?**
A: The power depends how fast you spin the windmill.The forward voltage drop of an LED is typically 2 to 3 V. Let's say 2.5V.A current of 20 mA (0.02A) will produce a bright light. That's probably close to what you get with a fairly strong wind turning your windmill.The power dissipated in the LED in this case is 2.5 x 0.02 = 0.05W = 50 mW.

**Q: Is included the elements, for example charcoal, aluminium or salt? And is included some pieces of science kit as tube, ect?**
A: It a simple kit,  included small slides aluminum, carbon, works fine but is small,  from kids 4 old years. Needs salt and water not included in the box.

**Q: Does this only work once? My son can't get it to go a second time. Wondering what to do.**
A: It will work multiple times. Make sure after each use to clean the battery parts with water and allow to dry before reassembling

### ⭐⭐⭐⭐ 2 things to watch out for during assembly to make it work great!
*by H***R on January 22, 2018*

I received this today in our RND Lab and assembled it right away. Had 2 issues that once corrected, the unit works just fine. 1st, they provide a detailed instruction sheet and it is simple to follow. They "clearly" show the RED wire at the bottom right rear and the BLACK on the other terminal. After assembly the light would not light up. As an engineer, I immediately started trouble shooting and found that if it was spun backwards the LED would light up. Of course being thorough (they recommend twisting the wires which I just can't live with), had to "de-solder" and then re solder the wires to the opposite terminals. Using our shop air compressor system and 40 PSI the LED lit very brightly. 2nd, the bottle cap adapter that they recommend adding oil to is molded with too high of a tolerance. To fix this problem, I sanded the very top edge until it was smooth (there is a very definite ridge ring that can be felt around it that is unnecessary). After that it easily spun around as it should. I've added a picture showing the 2 steps above. So, in the end, definitely an excellent product for learning and and the price is very reasonable. If it hadn't been for the extra work it would have been given it all 5 stars.
