BS homework....Evaluation!

"Sell a range of soap bars that float so they don't get lost in the bath. One obvious way of making floaty soap - other than choosing ingredients that are less dense than water - is to add air bubbles to each bar during the manufacturing process." Would this sell well?

This is a quite creative business idea which may increase the sales and don't use too much cost.As we all know,soap bars are slippery and easy being sliped out of our hands.And always,our bath full of water,and it's not easy to find it...if the bath is with a big size...it may take much time to find it.So,during the manufacturing process, a new business idea has been created which is really useful in my opinion.Consumers don't have to consider anymore about the "lost soap bar" and enjoy their relaxing time in the bath...~ ~....The main qualitative thing in this business idea is the process.Why don't we inject ingredients that are less dense than water???
This are my opinions:

• It may cost a lot for those special ingredients.
• Those ingredients maybe harmful for consumers health
• It may reduce soap bar's quality.

Just by easy idea,it's very easy to produce,and of course,it doesn't cost a lot.Just put in a little bit air,by air bubbles,and that's all,your soap bar is swimming.And also,because,there will be less real soap,so people will use all of the soap faster...And it may increase their sales by selling more.
Oh ye,and the younger consumers such as kids...may enjoy it whan it's swimming,so they could play with it.

And so on,I think,this business idea is impressive and I would invest in it.
