Who knew you could do this with a jam jar?!
Soap Pump Dispenser
Using a pair of pliers create a hole in the middle of the lid of your mason jar big enough for a soap pump dispenser that has been cleaned. Once the hole has been created, slot the pump in and seal with some super glue. Then fill your jar with your favourite jam and place the DIY pump on top and start to pump your jam out onto your toast! No more buttery jam!
