To make up the solution, introduce 500mL of hot water into a beaker on a
magnetic stirrer. Add the powder and leave to stir until it is all dissolved.
To test for complete dissolution scrape a bit up the side of the beaker using a
spatula. If the powder is not fully dissolved you will see small dark spots in the
liquid.
The sachet contains enough powder to make 1L of solution, but when I made
up a sample I dissolved the powder in 500mL and I thought the consistency was
just right.
When the powder is fully dissolved make the solution your desired consistency
by adding more water to a maximum volume of 1L.
To add ‘blood clots’ make a batch of port wine jelly and freeze it. Break up the
frozen jelly into pieces and mix with the artificial blood solution.
The solution is based on methyl cellulose so it’s probably best stored in the
fridge.
This product is sold as blood simulant for medical training centres and also as
stage blood. Mr Vivi put a dollop on the back of his hand and it stained him for
a couple of days.
Here’s a brilliant, very easy blood spatter experiment you can do without having to pull special equipment together –>>
