Make Your Own Kids' Glue

Dear users and authors,
do you have any ideas for safe children's glue?

Hello! I absolutely love doing crafts with my grandchildren. We use a glue made from flour and water
1. a large amount of paste

• 500 ml water
• 150 g flour

2. A smaller amount of paste

• 250 ml water
• 75 g flour

I whisk everything together with warm water until smooth. It will keep for a few days in a screw-top jar in the refrigerator.
Best regards, Sabine

Thanks, Sabine, and welcome to the forum.
When using this glue, will the model eventually start to smell bad, or does the drying process prevent that?
