Use a toilet paper tube or a kitchen hand towel tube hidden in a factory chimney. The company says if you have a large steam boat is to place the blaster in side the boat & you’ll will get many more times the sound. Other sounds include a busy city sound chip with police sirens & car horns tooting. What’s more important is that this is British made & there is even an updated sound blaster too! Ours cost us £30.00 s and the sound chips are £10 each. Take a look at their site for latest updates.
P.S you will NOT be disappointed…………………..
