"Goosebumps" exhibit with Emma

Above each black box is a terrarium, with either a hissing cockroach (!), tarantula (!), or king snake inside.  A tube from each terrarium connects to a black box below.  Are you afraid to stick your hands into the black box?  I wouldn't do it, even though Emma could see that the tubes from each terrarium were blocked and I knew that the exhibitors would never let people stick their hands in a box with a hissing cockroach, tarantula, or king snake inside.  But there was a rubber snake inside the king snake box!  Safe or not, I was too creeped out to put my hands inside the boxes. Weird, huh?
