I’m finally getting around to grading the 5-second timer labs my students did earlier this quarter. One of my students’ timers was a ceramic bowl with an amount of men’s cologne that burned for 5 seconds.
Unbeknownst to me until I read his lab report, he gives the following list of data as he was researching the experiment:
- after shave “balm” – nonflammable
- rubbing alcohol – flammable – 22 seconds
- Off bug spray – nonflammable
- after shave “liquid” – flammable – 14 seconds
- men’s cologne – 5 sprays – 7 seconds
- men’s cologne – 4 sprays – 7 seconds
- men’s cologne – 3 sprays – 4.52 seconds
- nail polish remover – 6.25 seconds
- nail polish remover – 13 seconds
- Visine – nonflammable
- men’s cologne lit with candle – 5 sprays – 8.87 seconds
- men’s cologne lit with candle – 4 sprays – 6.21 seconds
- men’s cologne lit with candle – 3 sprays – 5.08 seconds
Anyone who thinks research & development is not interesting should talk to this student.
