Suffolk teenagers can prepare fun and harmless pranks at the library next week for April Fool’s Day.

Suffolk Public Library is hosting “Pranks & Punks for Teens” for free at Morgan Memorial Library on Monday, and at the North Suffolk Library the following Tuesday. The evenings are for ages 12 and up, from 6:30 to 7:30 p.m.

Suffolk library services coordinator Shawna LoMonaco will share YouTube videos of do-it-yourself pranks and then help the teenagers build their own with craft materials. She said her children enjoy the prank videos, and they inspired her to organize a safe environment for prank ideas.

“It’s to help show teenagers that they can continue their pranks, while making sure they’re not harming others or getting others too upset,” she said.

Potential pranks will include bare toilet paper tubes with glow sticks inside.

“You put it in a dark closet and it looks like scary, spooky eyes are in there,” LoMonaco said.

Prints of “really gross looking cockroaches” will be cut out for amusement.

“When they stick it behind the lampshade, it looks like there’s bugs inside,” LoMonaco said.

Then there are the “earth-friendly” egg bombs. Actual eggs will be hollowed out and filled with ingredients like confetti or Fruity Pebbles.

“You see someone coming at you with an egg, you’re certainly going to expect a splat of egg yolk all over you, only to be covered in Fruity Pebbles,” she said. “It’s certainly not the shock you were expecting.”

She said she wanted to spark an interest in the teenagers for April Fool’s Day by doing what they enjoy.

“I think they like to be silly,” she said. “This is a way for them to do it in a safe environment with pranks that are safe, but still fun.”
