Now last time I got tea bags but they had no staples and even though they carefully cut the top and bottom off...

Re: Microwave Demonstration Equipment
I'm guessing you are talking about metal plates, grills etc They can just go into scrap metal bin if you have one .
If you also have the Wax prisms and lenses, can't see any issue with putting in general waste.
As far as the transmitter/ receivers go , it's just e-waste .

Re: Senses Boxes
Thanks Rosalie.
Personally I like the idea of petri dishes and essential oils . It would take up less storage space .
I may look at switching some of mine to what you are using . The Camphor smell is really strong and tends to overpower the others ,especially if left uncovered for too long.

Re: Experiment gone wrong
My head teacher says that Primary Schools are not allowed to do experiments with anything that's not edible . So using Metho is a breach straight up .
Which could explain why so many year 7 kids are always asking if they can eat everything .....to much molly coddling

Re: How to post a picture on Chemtalk
OK, just discovered that the Attachment size has a limit of 500Mb . So you can scale pics bigger than 800 pixels if the pic doesn't have too much detail in it . Maybe up to 1200 pixels on the long side . But for the most part 800 pixels will cover most Pictures. This forum must have a file size limi...
