Simon 3D - how to make magic beans?

I have the kidney beans, the cola and the sweaty frog. Simon won't combine any of them. Since it said they were to be boiled, I've also tried to put them in the witch's cauldron and in the boiling chilli. Nothing has worked. How do I do it?

Make sure you climb up the wooden planks to the top of the cauldron and then you will be able to put them in.
