Worldwide supply shortages have meant out normal bicarb supply is not available for a while (we will be getting it back in as soon as it is available).  In the meantime we have sourced this product that may need your recipe to be reworked  to get the same results.  1kg bags will be the original product for a short time only.  Bulk supplies have now been exhausted of the old supply

Bicarbonate of soda (colloquially known as bicarb) is the ultimate all-rounder. When mixed with citric acid, bicarbonate of soda will make amazing fizzing bath products like bath bombs, bubble bars and bath fizz. It makes a wonderful natural home cleaner and is often combined with salt or vinegar to this end. It can add polish or disinfectant qualities to products made with this intent. If you are looking for science experiments to amuse the children try a bicarbonate of soda volcano for heaps of messy fun. Outside is highly recommended.
