✂️ Craft Instructions: Turn the Template into a Mask
🧰 What You Need
- Printer + heavier paper or cardstock (65–110 lb)
- Colored pencils, markers or watercolors
- Scissors (craft knife for the eye holes – adults only)
- Elastic cord (about 12–14 inches)
- Hole punch for the elastic holes
Print the template at actual size (100 %, not “fit to page”) on thick paper.
Color the mask any way you like – the big shapes are perfect for little hands.
Cut along the thick outer line.
An adult cuts out the eye holes with a craft knife or pointed scissors.
Punch holes at the two small circles, thread the elastic through and knot it – done!
⚠️ Safety: eye holes, craft knives and hot glue are grown-up jobs. Don’t run or play rough while wearing a mask that limits your view – and never put elastic around the neck.
Play Ideas for Little Slime Monsters
Do a slime dance, moving wobbly and soft like gelatin. For a slime experiment, mix cornstarch with a little water – the goo turns solid when you press it and runs when you let go. Chase soap bubbles around the room. Then play Melt Down, where everyone slowly oozes to the floor when the music stops.
Fun Facts About Slime
Slime monsters only live in stories – but real slime is super useful in nature. Snails glide along on slime, which also keeps them from drying out. Tiny living things called slime molds can find the shortest path through a maze without having a brain. And cornstarch mixed with water makes a wacky goo that acts like a liquid one moment and a solid the next. Important: always do slime experiments with a grown-up.
