We are in a new millennium, yet not all of the things are modernized... what design concepts must be utilized for effective and safe restoration and cleaning materials?
:eyebrow:I agree to what I have read some time ago. Some information stating that the design of an elephant's trunk is suitable for cleaning narrow spaces because of its flexibility and the varieties of activities it can perform... other than that.. I am looking forward to see these new inventions for the future... a mimic from nature...
what about you?:weee:
sure, when we are waiting to be smart enough to find an alternative energy source that is good and reliable!
