Cement Balloon Garden Spheres

Materials
Liquid cement mix - 1 bag
Large latex balloons - 3-5
Cooking spray or petroleum jelly for coating - 1 can/jar
Directions
Inflate the latex balloons to your desired size for the garden spheres. Ensure they are tightly knotted to maintain the shape.
Apply a thin layer of cooking spray or petroleum jelly to the surface of each balloon. This will help prevent the cement from sticking permanently to the latex.
Mix the liquid cement according to the instructions on the packaging. Aim for a thick, paste-like consistency for easier application.
Carefully pour or scoop the cement over the balloons, covering about half to two-thirds of each balloon. Allow the cement to naturally drip and create an organic texture.
Let the cement-coated balloons dry and cure for at least 24-48 hours. Ensure they are placed on a flat surface or suspended to prevent them from rolling.
Once the cement is fully hardened, pop the balloons and carefully peel them away from the cement shell. Discard the latex remnants.
Smooth any rough edges or surfaces with sandpaper for a cleaner finish, if desired.

Variations & Tips
For a personalized touch, consider adding color to your spheres by mixing concrete pigment into the cement before application. You could also experiment with different balloon sizes and shapes to create a variety of spheres or even other geometric forms. For added durability, a waterproof sealant can be applied once the spheres are fully dried, ensuring they withstand the elements and maintain their appearance over time.
