One of our 10 yr old boys watched this with the 12 yr old daughter. The daughter jumped a little and let out a little shriek, the 10 year old I thought was going to shit his pants for as bad as he jumped and screamed. I was afraid anyone walking by our house would think we were murdering him. The other 10 yr old boy comes out and watches it and he jumps and shrieks a little. I wish I would have had the first ones reaction on video because it was priceless!!:00hour
