Science Fair Project

I remember a time when trolling wasn't just saying dumb things then laughing at people when they call you dumb.

Nah, already been done.

Oh, wow.

Contents cubes are usually made of (types of plastics, metals, and why).
Different types of lubes that are used (and not used) and why.
Commutators.
Perhaps memory methods for BLD solving and how humans are capable of them. (Might be harder to demonstrate.)
All else fails, you can always through out numbers and facts, but that'll be more of a presentation rather than a science project.

My science project is rate of improvement compared to different methods

Taking the same type of cube and using different lubes woud be interesting. If you do that please share the results!

How about building a robot that can solve the cube and race it.

heres my robot, its a brick with a battery. I win every time

Lol, lighting a piece on fire looks like a great way to track pieces for insertion when doing FMC! No way you'll lose track of that piece.

You could get all the Dayan cubes, and do an average of each one, (Taiyan - Zhanchi) and see how your times compare.

Rubik's cube on fire was awesome. I guess it beat putting on new stickers.

As far as science, the thing that's been argued here is whether the different plastics used in cubes have different coefficients of friction. It would be nice to have a real test of this done.

Early production of a given cube is supposed to use slipperier plastic. Is it true? Is the plastic even different? It seems that the Zhanchi's are currently new enough to be using the slippery plastic. The later plastic might have different components or be recycled.

There's a bunch of info on the web on how to identify different plastics. One biggy is density. The way you measure density very accurately is to determine the ratio of the weight of an object to the weight of the water it displaces. That is, measuring the volume is very difficult to do accurately; it's easier to weigh some water and then suspend the object in the water and see how much the water increases in weight.

I did a science experiment of whether I solve my cube when my hands are cold or warm. I got 3 seconds faster when my hands were warm

talk about gods number.

I would love to see this done. Plus if you presented it in a way that non-cubers could understand it, it could probably help out a lot of people on the forums as well. It is a tricky subject though, and would be hard to get people to understand within a limited time frame or space.

I seriously can't understand this. Are you sure your hands become slower, numb, and less agile when cold? It just doesn't make any sense...

When I'm cold (Which is almost always), my averages are about 4 seconds slower than when I'm warmed up. Sadly, the only times I'm ever warm is when I'm at school, or place my hands in front of a heater for 5 minutes.
