Final two hours for Mirobot!

Yes, yes, I know I’m a stuck record about this, but: you only have a couple of hours left to back Mirobot. The Kickstarter hit its last stretch goal last night, so the full package now includes the line-drawing robot, obstacle detection, line following and a speaker.

I’m delighted for Mirobot’s creator Ben Pirt, and looking forward to the production run later in the year.

The gloves conundrum

UCL chemist and demonstrator extraordinaire Andrea Sella, on his blog:

the wearing of gloves in the lab may, counter-intuitively, put us, our students, and our fellow lab workers at greater risk than riding their flasks bearback.

Do read the rest of his post, and likely the rest of his blog too.

I should talk to CLEAPSS about this sometime – Andrea’s comments on gloves make a lot of sense to me, but I’ve no idea what the standing advice for schools is. Ah, the simple life of not actually being a teacher.
