Check to see that there is no film stuck in the pump’s airway. If there is soft film there, remove it and rinse the straw. Lesson learned for your next drop, make sure that the water is hot enough and/or you wait the full 1 minute before shaking! If it is still not working, you are welcome to order a replacement pump, at no cost, here: https://thedailyroutine.co/products/replacement-pump
