@Andrestrujado I enjoy doing the bouncy ball across the temperature range (room temp to liq N2). Room temp very bouncy little noise , liquid nitrogen, metallic sound and does bounce may shatter if your very forceful. Dry ice temp no bounce!

@UncleBo80053383 @CLEAPSS @RSC_EiC @SciInSchool @ChemEdX I should add I place these in each of the fume hoods to enable students to do weighing of reagents (ca 1-5g) without waiting for a free balance. This is true time saver, however they do share the space with the odd incontinent acetone bottles. So not always the students fault😀

@chembameditor i find it of great benifit to the training of technicians supporting teaching. Great for confidence and development of the technician as a demonstrator in undergraduate teaching lab. It is fun and something they own.

@BaumV This looks great! Is it the kind of thing you could box up and mail out to schools to loan?

@DrKevinMorgan I think the demonstration could work, have done it on a larger 20 mL syringe column with 200 mg sample. You could get the students to do TLC analysis and demo the column, and distribute fractions.
