Start by mixing your concrete mix with water until you have an even consistency. Don’t make it too runny because it’ll be harder to work with (leaking etc) .
Spray the inside of your egg with PAM. This will help the plastic egg come off later. Than fill the bottom half of your egg with concrete mix and insert your small plastic egg in the center.
Attach the top half of your plastic egg. Wipe it clean and tape the crease to make sure it’s secure and doesn’t come apart while setting. Then lay it slightly on the side and let it set for 24 hours.
To avoid your candle wax from seeping out cover any holes in the top half of your egg. Make sure your egg doesn’t have snags on the inside as well (so your wax doesn’t get stuck to it once it sets)
REMOVING YOUR PLASTIC EGG! Okay so the top of your plastic candle should slide right off if you twist it. You can always warm it up a bit with your lighter if it’s not budging.
