I was on a bus today going for CDS (honestly I can't wait to be done with NYSC). The journey from Iyana-Ipaja to Oshodi, was a long one, because of the usual traffic, trust me the hold-up no be here. I was considering whatever I saw by the road and something struck me. I saw a tire patcher (vulcaniser: the term is debatable) using fufu to seal the bead of the tire with the rim! For our non-African friends that may not know, fufu is a whitish semi-solid food made from cassava, that's ingested by first dipping into a suitable soup and swallowing.
The spirit of science in me couldn't shake off the thought and I began to wonder and kept asking WHY? Like I said earlier, these guys have no formal education, so if I asked him why he was doing that he'd say it's meant to gum the rim to the tyre or something close. I thought about the myriads of physics and chemistry practicals these guys do every day without knowing the chemistry behind it. I still came back to the fufu application, checked the Internet and found nothing, save a post on wiki how that showed how to patch your tyre. Like others, it had nothing to do with the application of fufu. The post on wikihow, however, didn't mention any need to seal the bead and the rim again. These craftsmen wouldn't do this for no reason. I believe there's a purpose for the use of fufu.
I came to the conclusion that our #science gurus in
