Do the Spilt-Coffee Prank!
Make a realistic fake spilt-coffee prop using glue, brown paint, and wax paper; place it safely to surprise friends and learn color mixing and molding.
Step-by-step guide to make a spilt-coffee prank prop
Step 1
Gather all your materials and bring them to a clean table.
Step 2
Put the tray or cardboard on the table to protect your workspace.
Step 3
Lay a sheet of wax paper flat on the tray.
Step 4
Pour about 2 tablespoons of white glue into the disposable mixing cup.
Step 5
Squeeze a little brown acrylic paint into the glue until the color looks like coffee.
Step 6
Stir the glue and paint together with the stir stick until the color is smooth and even.
Step 7
If the mixture feels too thick add one drop of water and stir once to thin it slightly.
Step 8
Spoon a blob of the brown glue mixture onto the wax paper to make the main puddle.
Step 9
Use the stir stick or toothpick to drag out tiny drips and make a splash shape around the puddle.
Step 10
Dip the stick in more mixture and trace around the puddle to build a raised rim for realism.
Step 11
Wipe any spills from the tray with a paper towel to keep your workspace neat.
Step 12
Let the fake coffee dry undisturbed for at least 12 hours until it is hard and glossy.
Step 13
Carefully peel the dried fake coffee off the wax paper.
Step 14
Place your fake coffee prop on a safe flat surface to surprise a friend.

What can I use if I don't have brown acrylic paint or white glue listed in the materials?
If you don't have brown acrylic paint, substitute brown tempera or poster paint mixed into the 2 tablespoons of white glue in the disposable mixing cup, and if you lack white glue use any PVA/school glue that dries hard and glossy.
My fake coffee is clumpy or won't peel off the wax paper—what should I do?
If the brown glue mixture is too thick or clumpy when spooning it onto the wax paper, add just one drop of water to the disposable mixing cup and stir once as the instructions say, and if the piece won't peel after 12 hours, let it dry longer and gently lift an edge of the wax paper.
How can I adapt this activity for different ages so it's safe and fun?
For younger kids have an adult pre-mix the glue and paint in the disposable mixing cup and let them spoon blobs and drag drips with a finger, for elementary kids let them stir and use the stir stick or toothpick to make splashes, and for older kids challenge them to tweak paint ratios, build higher rims, and make multiple puddles before the 12-hour drying time.
How can we make the fake coffee look even more realistic or personalize it?
To enhance realism, sprinkle a few instant coffee granules into the raised rim while the brown glue mixture is still wet for texture, or after peeling the dried fake coffee off the wax paper brush on a clear acrylic gloss sealer and glue the prop onto a saucer to stage a mug spill.
