What is the difference between the penguin model and the crystal model?

Really no difference. But they are not making the Penguin anymore. They both use the same glass bottles and CO2 refill canisters.

My daughter has the Penguin model and mine is the Crystal. The Crystal is plastic on the outside and the Penguin in medal. They take the same CO2 cartridge and both have glass bottles and produce the same quality carbonated water. The Penguin is much more expensive and I couldn't see the point in spending the extra money for a slightly higher quality look when the performance is the same.

I have not purchased the other. The description appears the same though. I also saw this version for $29.99 with free shipping.

I don't know the difference but I was not able to get this device working at all. I pitched mine in the trash after trying to get it working with the software for weeks.

I have only used the medium and I think the small would be the same shape of cube probably but just smaller. I can tell you this though...usually how this thing works is that it makes the ice and when the cubes are first made they are kinda hard but by the time that the bin is more full...when you take out the cubes they are nice and soft and perfect for people like me who like to eat ice without killing their teeth. The shape of the cube is like a bullet with a hollowed out center so they are easy to chomp on if that's what you like but not too soft so that they melt right away. I let mine run all the time and it makes ice till it runs out of water and it has been working great.

We are not sure but we love it. It is very sturdy crystal. We actually bought another one as a gift and receive many compliments on it.

I think one difference might be the amount of ice cream it makes. The model I chose makes 2 quarts (almost). Depends on the recipe. I am not sure the specs on the other or the price and can't tell you the difference being worth it. Sorry. I love this one. I did find not to turn on the cooling with the beater. That causes the first ice cream into the machine to freeze on the bottom of the bowl prior to the other and hard to remove. Turn on the beater and then add the ice cream then after a minute or so turn on the cooler button.

I have found no differences between the different diffraction glasses that I have purchased from Amazon. I have been buying large quantities for a couple years now to pass out to 8th grade science students in an Expanding Your Horizons project that I volunteered for. We use them to describe how Optical Emission Spectroscopy works in our lecture called "Chemistry of Light" I have never even tried them under black light, but will look into that for future reference. Not sure about the actual diffraction grating sizes being used but we are just looking to get the children's interest sparked so we haven't been very scientific about it.

It does not form crystals. I don't think you can control the speed of the paddle but I have never tried. P.s. I love the machine.

they do not have any difference... both do not have a digital display ... only the oldest model has.

The crystals are plastic. I bought the pink one. My little daugther love it,and me too.

The Crystal and Penguin models will definitely not take these bottles. I believe the other machines are all capable of handling the 1L plastic bottles. I have the Source model and they work great with it. Mine came with the non-dishwasher safe stainless steel 1L bottle if that helps.

Sorry, I don't know the difference in the models, but they do sound very similar in the description.

I am not sure the crystals this has is the same as what I get, but they work just fine. I buy them at the only local grocery store that carries them, so I only go to that store. I've seen them advertised in pet supply stores, but I sure wish more people carried them!

Juan, though I'm not sure, I believe the difference is in the color of the unit----P = pink, W=white. I have seen both colors. Also it comes in blue. Hope that helps

Basically they are the same thing. One is advertised to be for strenghth which is more expensive and the other is just a clear gel to apply gemstones and other 3d items so its cheaper. The clear gel will also make your nails grow.

They both look exactly the same in function, its just the 21 is a bit smaller and has more plastic. Check this guy's video on Youtube and it breaks down the ICE-21. http://youtu.be/jPPdSCHBTR4And he did the same for the ICE-30BC: http://youtu.be/Q40vHKdJmpY

I looked at the cheaper version and I don't see much difference except for the body model itself. This wasn't available when I bought the expensive one. Go for it. Can't go wrong. They both teach the same concept. Enjoy--the product is fun and very realistic!!
