In other words, itвЂ™s a storm in a slimepot.ДЄugust was all about carbon dioxide, after a heatwave spread across Europe and there was, bizarrely, a carbon dioxide shortage which had an impact on all sorts of things from fizzy drinks to online shopping deliveries.

Unless your child is eating slime (donвЂ™t let them do that), theyвЂ™re never going to absorb enough borax to do them any harm. In other words, itвЂ™s not appropriate to measure the total borax content of the slime and declare it dangerous вЂ“ they should be looking at the amount of borax which is absorbed during normal use. Plus, the limits that I was able to find are migration limits. ItвЂ™s all rather questionable, since itвЂ™s not really clear which safety guidelines theyвЂ™re applying and whether theyвЂ™re appropriate for slime toys. This time it flared up because the consumer magazine and organisation Which? kept promoting research that, they claimed, showed that slime toys contain dangerous levels of borax. July brought a subject which has turned up again recently: slime. And will probably keep on rearing its slimy head. Did you know you can make indicators from the leaves of Christmas poinsettia plants, too? Who knew? You do, now! Check it out if youвЂ™re looking for some chemistry to amuse yourself over the holidays (I mean, who isnвЂ™t?). In June I wrote about strawberries, and did a neat experiment to show that strawberries could be used to make pH indicator. It turns that this was, and is, a real risk вЂ“ so if you keep fish and youвЂ™ve never heard of this before, do have a read! May featured fish tanks, following a widely reported story about a fish-owner who cleaned out his tank and managed to release a deadly toxin that poisoned his entire family.

The bottom line is that everyone in the UK should be taking a small vitamin D supplement between about October and March, becauseВ northern Europeans simply canвЂ™t make vitamin D 3В in their skin during these months (well, unless they travel nearer to the equator), and itвЂ™s not a nutrient we can easily get from our food. Check out the post for more info.ДЄpril ended up being all about dairy and vitamin D.ДЄpril was all about dairy after a flare-up on Twitter on the topic, and went on to talk about vitamin D. ItвЂ™s my quick and easy way of fact-checking online information вЂ“ an increasingly important skill these days. In March I recorded an episode for the A Dash of Science podcast, and I went on to write a post about VARD, which stands for Verify, Author, Reasonableness and Date. In other words, unless youвЂ™re actually working with it вЂ“ in which case you should have received safety training вЂ“ thereвЂ™s no need to be concerned. In a report, the European Food Safety Authority said that the health concern for BPA is low at their estimated levels of exposure.

ItвЂ™s not a harmless substance by any means, but it wonвЂ™t surprise anyone to learn that the risks had, as is usually the case, been massively overstated. BPA is also used in a number of other things, not least the heat sensitive paper used to produce some shopping receipts.

Anyway, BPA is a chemical in many plastics, and of course plastic waste had become вЂ“ and remains вЂ“ a hot topic. ItвЂ™s our penance for daring to enjoy Christmas. ThereвЂ™s always one around January/February time. In February I wrote a piece about BPA (Bisphenol A), which was the chemical scare of the day. February featured BPA: an additive in many plastics.
