We used to burn marshmallows when I taught HS

How did you come up with the idea to use sand? Genius!

Tremendous improvement over using cotton balls or candle wicks

When we tried this with a cotton ball, we had to do it in the fume hood because it was so smoky

I see that you are wearing gloves. Do the students also wear gloves?

Where did you get the Put Put Boats?

Love the put put boats!

Show the worksheet associated with the lab again,

Q=mc(delta)t for water, how is that balanced for heat of combustion for ethanol or biodiesel

Have you ever used un-transesterified oil to compare the energy difference between oil and FAME? And maybe the oil won't ignite; which is also a teachable moment!

Glad students don’t need gloves. I wondered how you avoided melted gloves.

An Appleseed processor!!! A blast from the past!!

outstanding webinar, diesel fuel today was $4.59 gallon so 200 gallons a year is close to one thousand dollar production per year, nice break even question for lab production facility/ future grant writing meathematics
