In design this half term we have been doing Rube Goldberg machines. I made a balloon popping machine. It took 16 failures and on the 17th I got it. It included dominoes, a pin, a hot wheels car shooter, hot wheels track, a bouncy ball, a glue stick(to hold the balloon in place) and blue tack. Sorry I cant show you it dose not let me up load it for some reason. 🙁
If you want to see it it is in my teams folder.
