Materials

- 500 ml White vinegar

- 35 Baking soda

-500 ml Boiling water

Tools

-Coffee filter

-Spoon

-Saucepan

-Sachet

-Funnel

-Trombone

Step 1 -

Put 500mL of vinegar in a container and gently add the bicarbonate of soda (you will see a gas being released as it foams, this is carbon dioxide).



Step 2 -

Pour this solution into the 500mL of boiling water in the pan and allow the solution to evaporate: you will notice crystals forming at the bottom of the pan.




Step 3 -

Remove the crystals from the bottom of the saucepan and crush them so that they fit into the container (in this case, the Pompotes flask).




Step 4 -

Bring the water to the boil and melt the mixture in the flask at a low temperature until the mixture is liquid.




Step 5 -

Leave the sachet to stand in the open air, avoiding any shocks.




Step 6 -

Add the paperclip and then stir the sachet to crystallize the sodium acetate which, being exothermic, will provide us with heat!




Step 7 -

To reuse it, repeat steps 4 and 5.
