Float soap bars

There is a new product which is daily commodity.Soap --- a float soap. What is the characteristic of this soap? *That's mean you won't lose it in the bathtub when you have a bath.And there are two ways that you can make it float.One is choosing ingredients that are less dense than water ,and the other one is to add air bubbles to each bar during the manufacturing process. That's a simple introduction about this soap. So next let's discusses about this idea.
Let us look the benefit about that: That is really can help to solve a problem which is when you in the bathtub for a relax bath and then you can't find your soap... Because it fall in your bathtub, and you know it will be very difficult to find out it... so what could you do ? To feel all the bathtub for find it?Or make all of the water run off? And you have no choice you must find out it,not only because you need it but also if you don't pick it up it will melt.So if you find it will be waste of your time ,and will make the water in bathtub become colder.In one word if you soap fall in the bathtub when you taking a shower,I think you are very unlucky so poor.Therefore if you have a soap like float soap ,you won't need to worry about the problem like that... I think it will be more convenience . And also I think if we use the second way which is to add air bubbles to each bar during the manufacturing process that really good ,like that's may make the soap looks more beautiful, more special.That's also can become a USP.
Then let's talk about it's weakness: There are two points first one is the cost of the product the other one is about the market.So the cost will be very high I think because it should need use the new technology and also if you want to add the value of the small soap to increase the profit you need cost a lot on the packaging on the making shape to the soap.So it must be a lot of cost. Then we need talk about the market So I have a question that is Does anybody need the float soap? Does it useful to anybody? When a new product is sale the most important thing is the demand of the product.So I have think about if the soap in the bathtub which has full of the water for a long time it must will be melt.Getting smaller and smaller.Basically if we have added air bubbles in the middle of the soap the weight of the soap already is very little.So the time of one soap can be used will be very short.So that mean people may consider which one should they buy the traditional one or the new one?Which one will cheaper for use a long time,and don't change? Of course the answer is the old one that most of people can believe it.
So for this reason I don't think the soap will sell well.
