Make one side a lot smaller. Come up with like little tiny spoons to make their wheel a little bit bigger. These are the products, I am going to test rice roll shaker, Awada, chino, grape peeler, gyoza maker, carrara wash rice roll shaker. His purpose in life is to make a sushi roll with just a couple of shakes of the wrist. Today we'll be making a salmon and cucumber roll, one of my favorites. Let's see how effective it is. Let's put in some rice and I'm not sure how much to put in, but I'm gonna put in what I think is going to be a reasonable amount and let's lay in a salmon and the cucumber, I think I'll put a little bit of rice on top. I have some nori that is cut to size. So I'm gonna feed it into the slot now. In theory, I'm gonna shake this and the jury is gonna wrap itself around and create a role. Let's see if that magic happens. I might say the magic didn't quite happen yet. Try this this time. We're gonna hold it vertically. Salmon is closer to the middle, at least it has some rice wrapped around it. Okay, let's try the Nuri again, I'm gonna feed it in as far as it wants to go and it is, it rolled itself in so I didn't know what to expect. It seems a little magical that it would just wrap itself into a cylinder by just shaking it. Is it the tightest sushi roll? Maybe not, but it definitely worked itself into a sushi roll. So let's compare that to the centuries old way of rolling sushi. The end result seems a bit tighter packed. The shaker didn't involve nearly as much technique to understand how to use it because of that. It had some advantages, although it was a pretty loosely created sushi roll in terms of effectiveness on a scale of 1 to 5 for the sushi roll shaker, I would give it a four. I thought it was rather loose sushi roll but it did work and it worked almost the first time I think trying this left hand to the right hand. It's not gonna make a big difference. There's just this ball that you need to hold on to this round object, it's not gonna slip in the left hand or right hand. So I don't think I'll learn anything by using this left handed for usability. I would also give it a four out of five. It's a little bit of practice though, it takes less practice than rolling Sushi by hand. Let's talk about a redesign and I think this part of it is kind of okay holding it like this. I would at least try to experiment with elongating the handle to see if making it longer it's going to be any more effective at giving its um agitation up here to get it to roll better. The other thing is, this slot is a little fussy. The nori is not necessarily perfectly flat. What I would do though is I would make this a little more generous and funnel like so it's a little easier to feed the durian. Aside from that, this is such a simple object. I'm not sure what other improvements I would suggest for a buy rating for the rice roll shaker. I would give it a four out of five. I would think it's worth it. Just for the experimentation, you would probably have some fun trying it out. So it looks like there may be a lot of rice rolling in my future. I'm never gonna give you up. I'm never gonna let you down a water chino designed to foam up milk. So you can become a sculptor with your morning latte in front of me or all the makings for a three D latte with soy milk as far as I can tell. The soy milk needs to go in first. I am going to place this in. I'm gonna place this in. Okay, so this needs to be up because there is a tab here, we should be foaming. So let's give it a couple of minutes because it's not looking like there's a whole lot of foam going on here. Okay, we're at the three minute mark. And I have. So I milk. Let's see if that liquid part runs out. If I have any foam left at all. I've got some very drippy foam that I don't think it's gonna hold itself together. No, it's just not stiff enough to uh, to make anything recognizable. And I've actually just ran out of foam. Well, that's not what I expected. It doesn't look that happy, but neither am I. I refuse to admit defeat. No espresso for me this morning. This is more depressed so, well, the water chino was a bust, but let's see how we do with an electric froth. Er, See what I do get. It's thicker than the water chino. I was hoping to go for a bear. I think I got a little piggy thing going on in the cup here. This little piggy tastes fine. I can't really say I'm pleased, but there's some level of success in terms of effectiveness on a scale of 1 to 5. The Awada chino get zero didn't do anything. So it doesn't even deserve a one yikes. Normally at this point, I would try to use this left handed, but it's gonna fail Left handed, Right handed. It doesn't really matter on a 1 to 5 scale for usability. It doesn't even deserve a one. Should be a really good example of how not to make something usable. It just was not easy to turn it on. It wasn't easy to assemble. It wasn't easy to align the little tab to turn the switch on. It wasn't easy to spin the on switch just there was really nothing about it that screams out usability. Let's talk about a redesign and this one's tough. I don't have any instant solutions on how to make this work. I have seen foaming devices that would be simply a cylinder with a screen like hand pump. It's got a base like that milk up to here and you start pumping and this starts creating some foam. Now, could this turn into something that you can make artwork with? First of all, you have to foam this up so it's thick enough so you can make a three dimensional shape and maybe what I would suggest is using a device like this. But creating some sort of spoon like tools which would have various shapes, figure out how people are sculpting clay. Look at what those shapes are like and I would replicate those in a set that would come along with this foma. It's almost two different things. These little devices to make the shapes and to make a cute little bears or frogs or pigs separate from the fact that you also have a fomer that will work. That doesn't require making artwork. So in terms of a buy rating, I would give the cappuccino of five out of five. Oh wait 9 to 5. I mean zero, sorry, Awada Chino. I expected really cute little things from you. I got nothing grape peeler in front of me is a great peeler whose purpose in life is to allow you to peel grapes. So I've got a bowl here of chi ojo grapes. They are traditionally served in japan peeled as a dessert. Great number one. They are really tiny. Let's see if I just go at it. So I'm going to insert twist, which is the way I think I'm supposed to be doing it and I've got the inside of a grape and two halves do a couple more first impression is that this wire part seems larger than it should be. Let's see if I come around the round edge, if I can extract a whole grape on the inside and that did work. I do have a peeled grape, I feel successful, it's faster to eat than it is to peel. So these grapes have nutrients in the skin as well as in the flesh part and I'm just bringing that up. I am raising awareness. Let's try it this way perfectly fine. Let's see how the grape peeler compares to using these grape peelers in terms of effectiveness on a scale of 1-5, I would give it a Let's give it 3.5. I think there could be some improvements and it is rather time consuming, maybe there are ways to speed things up. I'm not going to try this left handed because it's not a whole lot of force to this. You've got to hold the grape and the tool at the same time. I think there are some things that could be improved a bit, but I don't think I'm gonna learn that much from trying this with my non da dominant hand. So final rating two out of five. I think there has a long way to go in terms of usability. I think there could be some significant improvements. Okay, let's think about a redesign. I would start with actually thinking about the wire part. This seems large to me for the tiny grapes. What is curious to me is that these are not that difference and grapes vary a lot more than these shapes. So I would probably make one side a lot smaller and the other side somewhat bigger. The other thing I would do is think about the shape of this, this would be round, this would be round, but bigger, this will be round. And the reason I want to do that is because you want to be able to spin this may be a slight over would help. So I would simplify the shape and then as mentioned, make one wire rather large and pointy and the other one go a little smaller so that we're not breaking the grape. I think that would be it. If you really want to peel your grapes. I think there are some improvements that could be made to this great appeal. So in terms of a vibrating, I would give it a four out of five because I don't know what the alternatives are appealing by hand. Didn't quite do it. Gyoza maker. This is designed to make filling a gyoza and absolute delight. Just look how fun this looks. It's got all these parts, it's got gears, it's got cranks, its got things going on. I am overly excited to get into this. Let's see how effective it is. So, I am going to follow these japanese instructions put this in place. I'm going to use this as what I think is the target fulfilling. I've got a mixture of pork and scallions in here. I think maybe this is what I'm supposed to be doing. I'm not sure. Let me close the top crank. Think positive, I may have overfilled it. Whoa! It's using out. Whoa! Where did it go? Hey, here we go! If you're gonna make yo sis at home, this could be the way to do it. And I am still having fun. Let's do another one. Place the dumpling wrapper on the round side, wet the outside. Try very little filling. This time. I am learning that a little bit of filling goes a long way close the cover drawer is in place. This is coming around. I am not using out that hopefully was a good amount of filling and I feel so successful. I think I have perfected the technique. Okay, let's cook up this dumpling order pizza looking good enough to eat. So let's do that success tastes like pork and scallions. So I am feeling pretty good about this. I thought it was easy to do. They sealed up pretty well. Nothing fell apart as I was cooking them up. So I'm feeling like I would not only want to use this, but I think I would want to use it again and again and again. Let's see how the dumpling maker compares with filling a grocer by hand. Okay, so these are not looking that bad actually.
