Little plastic dinosaurs can be inexpensively purchased from party supply stores or online, making this not only an easy project - but a frugal one as well. Hide your eggs in a sand box, in a dinosaur nest made from shredded paper in a kiddie pool, or around the house or garden for the ultimate prehistoric egg hunt

  • Step 4

  • Step 4

  1. Preheat Oven to 250 degrees.
  2. Mix the Coffee Grounds, Water, 2 Cups of Flour and salt in a large mixing bowl
  3. If desired, add the sand to the mixture - this will make the eggs more grainy in texture which is fun - but by no means essential. You can also add a small amount of paint to the mixture (1-2 tablespoons) if you would like to add some color to the eggs.
  4. Form a small amount of the mixture into a ball and flatten into a disc. Place a dinosaur into the middle and shape the mixture around the dinosaur until it is completely covered and the mixture is formed into an approximate egg shape.
  5. Place the remaining 1/4 cup of flour into a bowl and roll the egg that you have just formed in it.
  6. Place on the baking tray
  7. Continue until all the dinosaurs have been formed into eggs.
  8. Bake the eggs in the oven for 40 minutes. Then turn the eggs, and return to the oven for another 40 minutes.
  9. remove from the oven and allow to cool. Ideally the eggs should then be left for at least 24 hours before being used to ensure that they are hardened
  10. Hide the eggs for the children to find. A great way to do this is to bury them in a sand box or even in a large container of potting soil. or you can hide them around the house or garden.


  1. Children should be able to simply break these apart. But it is also fun to use "tools" to try to open them - such as play hammers - or real hammers, with supervision of course.
  2. Most coffee shops are more than happy to let you have their used coffee grounds which saves you having to drink a lot of coffee before you can do this project!
