How do people make not real but fake fossils with soil or sand help?

Answer 1

for my daughters science project here is what we did.

1/2 cup salt

1 cup flour

1/2 cup cold brewed coffee

1 cup used coffee grinds

mix together add more flour if necessary until it is like really really thick Pizza dough.

flatten in a pan sprayed with cooking spray. find shells, bugs, leaves, fish bones or other things to make impressions with. spray the items before pressing them into the "dough". let dry for about 12 hours then remove the items so that the dough under them dries completely. it takes about three days for a whole tray to dry out. it looks like real fossilized dirt!!! the salt re-crystalizes giving it a cool effect. and the impressions are really clear. and they smell good too!

I don't see why you couldn't use a similar recipe using dirt instead of coffee grinds and water instead of liquid coffee. try it, you might be surprised.

Answer 2

People can make fake fossils using soil or sand by mixing it with water to create a moldable paste. They can then press objects like bones or shells into the paste to create the impression of a fossil. Once the paste hardens, the objects can be removed to reveal the fake fossil.
