Klassic KL-100 Premium Quality Plastic Green Watering Can for plants/ Garden/ with Sprayer (5 Liters)

I have tried this but it doesn’t work like shown in video. Only 10-20% of water comes out easily after that vaccum is created inside so no more water will come out and u have to squeeze it too much to make the remaining water come out or u have to drill another hole in bottom for air but water will keep leaking from that hole
