I love QR codes and have been enjoying the PeriodicVideos QR poster for a while. However, I was really excited to receive a QR code recently that was for Chemstuff! So thought I’d better share it with everyone…
Many thanks to Miss Wilson for this!
QR codes are 2d barcodes which you can point your smart phone at and with a very simple app you can collect a lot of data or find out a lot more information about something.
Do have a look at the PeriodicVideos poster as it is very impressive!
