Using a paint brush and or spoon cover whole egg in the paste , be sure to make it thick for a better reaction !

Now you can use an eye dropper (good for hand eye coordination ) or pour from it on and watch the reaction happen . Make a prediction on what the kids think will happen and then observe , ask questions , what is happening , help them to describe what they are observing to extend vocabulary . Listen to the sound of the reaction what do they hear? Enjoy and they can keep adding !
