clynt18,

Thank you for visiting the SB forums. Can you be more specific? Is there a science fair project involved that you'd like to get advice on?
Hope this helps.

Hi,

Most interesting question. A quick Google search added banana sap to the ingredients list. I just typed: "How to make liquid eraser from chalk dust" and Google auto completed the search with "and banana sap".

I was curious so I searched for the answer but I didn't find a good answer. Let me know if you find one. Another option is just to try it: Make some chalk dust and mix it with banana sap and test it.

If this is a project, it helps to post more information. If you are just curious, give it a try...

Happy erasing... :)
