I noticed some are attaching word docs in an attempt to attach a picture , so I thought I'd do a quick tutorial . First off , there is a size limit to pictures . They must be no larger than 800 pixels on the longest side. You need to resize pics in windows "Paint" or other picture software...

Don't feel bad about chatting to the teacher. We all make mistakes. Absolutely Merilyn , I must drive my teachers bonkers at times , but better they know ahead of time if there are issues . regarding the Calcium Fluoride , sometimes teachers deliberately ask for the impossible .In this case they ma...

Made an adapter in the 3D printer and found a bit of spring that lengthens the contact in the base.

if anyone ever needs one , PM me for the .STL file

Got a Power supply for our spectrum tubes as this year we had a new physics teacher that was a bit nervous with induction coils . Plugged an old Tube in and it ran beautifully with a nice constant glow compared to the flickery results that an induction coil normally causes . New Spectal tube PS.jpg ...

I wish Riskassess had some middle size labels . It was your dilemma which made me make my own Rosalie . My OCD is strong. I still will only use the same coloured pegs to hang an article on the clothes line . :oops: :crazy: Regarding leaving a legacy , that is also something that always plagues me . ...

OK , thanks . I'll probably just Alphabetically store them then . The Tubs probably aren't essential , but after finding so many cracked glass jars recently and contents that had ended up on the wooden shelves , I thought I'd just do it as a precaution . And I can Dymo Label each Tub with contents t...

Recently I have finally seperated our chemicals into DG classes .....yeah , I know , but my predecessor said it made it too hard to find anything unless they were all in alphabetic order . :whistling2: So , now I have a piles of chemicals in each group and I have purchased about 80 plastic tubs to p...

There . Apparently every-time she turned her back to write stuff , they’d start throwing stuff . Back on topic , We make Sherbet in the Labs . Have a dedicated set of morter and pestles and stuff thats kept in the staff room for this prac . Kids get to take it home to eat . Just curious - why do yo...

LOL , I've been asked to bring in 25 Lemons from my tree tomorrow .Apparently they are making pickled Lemon
Shertbet is being made as I type .

I've got mine from Haynes recently . I got some from Serata MTA but they have a funny size dropper lid that doesn't fit anything else. The Black Silicone teats from MTA are quite resistant to most things except acid . They quickly perish with Acid . The Red Rubber ones are better for Acid still . So...

Back on topic ,
We make Sherbet in the Labs . Have a dedicated set of morter and pestles and stuff thats kept in the staff room for this prac . Kids get to take it home to eat .

I wish I had taken a picture of one of our Labs yesterday . It was a down right disgrace. Some kid had pulled out a Peanut butter Sanga ....like those are banned anyway ....and then proceeds to smear it around the classroom . Then some other kid pulls out an apple , takes bites and spits them everyw...

Leave it plugged in .
Plugging and unplugging usually involves wiggling and wiggling loosens and weakens things .
Also when the Tag tester comes , how will he print "electronic Balance " on the Label if its just a loose cable .

If the teachers don't want to take it home for their dogs , it goes in the skip . Same logic as Merilyn . Bins stink long before they are collected and my stuff probably doesn't make it dramatically worse .

Wow, good find. We have one, its the same size as our flam liq, I think 200L approx. It was here when I got here. I think it's great, stores everything and easy to find it all. Thanks labbassistant I told SAM about all this and with out question and the usual rant about having no money ,BOOM , Flam...

Well I'm really having a fine time in the Chem store . After cleaning up a busted jar of Magnesium Powder , I went looking for all the Flammable solids and making a collection of them when I discovered two jars of Ferrous Sulfide have expanded and cracked the jars . I'm getting quite nervous that la...

Found some more disintegrating Jerry Cans . These ones looked OK until I gave them a squeeze .They crumbled instead of squishing. Doubt it was 0.001HCl that did this , perhaps it had something else in it before it was repurposed . Be wary folk , seems these things may have a time limit . BTW , these...

WOW Bigmack, the things you so find. Yup :crazy: ....this is what happens when you inherit someone's job that liked to keep everything :whistling2: So the I discovered the practicalities of disposing of 100gms of this powder . Firstly , its this much . 100gm Magnesium Powder.jpg I started with abou...

Just discovered this . Needless to say I'm a bit nervous dealing with it . obviously it has slowly absorbed moisture as our Chem store is cold and damp and has expanded and cracked the jar . There is now a split about 1-2mm wide that is exposing more air and moisture . I'm going to keep a small amou...
