Car Maker Kit Thingy

A long time ago, my mom gave this to me for a present. I call it the car maker kit thingy. I didn't actually start making the car until a few days after I got it. (It was actually meant for two cars so that you look twice as dumb when you mess up.) The kit comes with some plaster of Paris, but I call it flour because there's no difference to me. It comes with a cheap plastic mould to pour the flour in and stickers and a blo-pen and varnish and paint and wheels and wheel holders and finally, a measuring cup.
The instructions told me to take the measuring cup and fill it three times with the so called "Plaster of Paris" and pour those in a plastic cup. Then I had to take one of the buckets of paint and pour that in there as well. Then I had to use the measuring cup and fill it with water and pour that in too. Then I had to mix it all up 'till it looked like melted ice-cream. Then I had to take the bottom part of the cheap plastic mould and fill it up wit the mix. Then I had to take the top part of the cheap plastic mould and put that on top of the bottom part of the cheap plastic mould. After that, I had to wait a whole entire hour for it to dry. Then it was an hour later. I took the blo-pen and spray-painted the car blue. I got tired of waiting for another hour so I skipped to the next step. I painted the varnish on and I got tired of waiting for THAT hour so I skipped to the next step. I was adding the stickers but since the varnish wasn't dry, the stickers peeled off and ruined the car.
I tried building another car and I actually waited and the car looked perfect. Then a minute later, it got lost. Let this be a lesson to all of you who have little brothers and sisters.
