The experiment was done such that it was intended to find out the degree of adhesity of different types of plasters. There were 4 plasters tested, namely, A, B, C and D. each of these have a different degree of being adhesive and this is what the experiment was set out to establish. In that respect, the experiment was founded upon the concept that depending on the degree of adhesiveness of a plaster, it gets to pull out different numbers of hair from the skin of an individual. This is the attribute that was used to design the experiment and it led to a remarkable result that is indeed plausible. Different people were used in the experiment in an effort to ascertain the results. The human skin is made up of some hair particles that can come out readily in the event that the skin is subjected to the throngs of a plaster that has adequate level of adhesive strength. As such, the different plasters were glued on the skin of an individual one after the other. Starting with the plaster A, on to B, then C and finally D, the plasters were stuck on the skin of an individual. In each case, the plasters were pulled out in a half and an observation made on the effect that the plaster had on the skin. Each of the plasters was observed to have a different effect on the skin of an individual. It was made sure that the portion of the skin where the plaster was suck had hair and in that regard the effect on the hair was observed. Some of the plasters had the effect of pulling out fewer hair particles than others. The number of hair hat was pulled out by each of the plasters was then counted. This was recorded against the plaster type for each individual. Different instances of the experiment were conducted such that for each instance, different numbers of individuals took part in the experiment. In most of the instances, there was just one individual taking part in the experiment and in that respect different ...Download file to see next pagesRead More
