Thank you so much for your detailed response! I'm hearing the hairspray idea for the first time but it sounds very interesting!

<p>Silicone based materials will mostly reject water. There are a number of lubricants that are silicone based, but they aren't necessarily in every home.

Thank you so much for all the suggestions! I'm trying to use chemicals easily available in homes to make this art project but if i cant find anything that works, i may change my topic and go use one of the products you mentioned above!

<p>I'm doing an art project which involves a chemical reaction (ideally available easily like alcohol, bleach, acetone etc). I'm using acrylic paint/ ink on glass. I want my painting to have fractals, something like the image below to make it blister. Any suggestions on which chemical I can use?</p>

When applied to glass in the proscribed manner, it caused bubbling within the areas to which it was applied. One can apply it to the entire glass or to selected areas as desired.

Another hydrophobic coating is known as [NeverWet](https://www.neverwet.com/). It may not be perfectly transparent, but that might not be a factor if you're removing the acrylic from the glass after drying.

My search for other products using "hydrophobic coating for glass" provided many results if the above is not practical/useful for you.

I've been informed that acrylic removed from glass is called "strappo."

Adding a suggestion due to the "in home" comment...

Silicone based materials will mostly reject water. There are a number of lubricants that are silicone based, but they aren't necessarily in every home. Substances that are petroleum based, such as petroleum jelly and petroleum lubricants (WD-40) may also create a surface to reject water, when applied to glass.
