Put a large pan with non-stick coating on low heat, melt butter.
Add the marshmallows. Stir until they all melted.
Measure rice, add into the melted marshmellow and slowly stir.
Cover a baking dish (or any dish) with cling film and put the mixture on it. Cover with film and squeeze it well.
Now the most important part - creation! Use some oil as soap and put on your hands.
Pull a piece of mixture and shape whatever you want (heads, bodies, wheels, fingers like we've made here.)
To make marshmallow dough for decorating
Put marshmallows in a bowl, pour a few drops of lemon juice or water and put in the microwave or in a hot oven for 30 seconds. (They should increase three times in volume)
Add in the liquid food coloring. (3 drops - a gentle color, 7-10 drops - bright, saturated)
Stir well to distribute color evenly.
Pour 100g icing sugar and continue to mix.
Pour the remaining powder on the table, put the dough on it and mix untill it does not stick to hands and feels like play dough! Add more icing sugar if it is still very sticky.
Now you can make different figures or roll it and make covers. Just use a tiny drop of water to stick small details.
Use smarties or mini smarties as eyes, noses and details for your figures.
