Is it easier to float in an ocean or a freshwater lake? How do you make an egg float? It’s time to defy gravity (well, not really, but the results are still amazing), with Nancy B’s latest egg-cellent egg-speriment! Try this at home using items found right in your kitchen.
Here’s what you’ll need:
• 2 beakers (or clear drinking glasses)
• Salt (a good pour as opposed to a sprinkle)
• 2 raw eggs
1. Fill both glasses/beakers with tap water. Be sure to fill the water to the rim of the beaker or glass.
2. Carefully place one of the eggs into the glass/beaker. What happens?
3. Next, pour several heaping tablespoons of salt into the other beaker/glass and stir to dissolve the salt. Gently place the second egg into the salty water. Are the results any different?
This experiment shows us that objects float higher in salty ocean water than in freshwater.
Why does this happen? When the weight of the displaced water – the water that pours out of your beaker/glass when you drop in the egg – is LESS than that of the egg, then the egg will sink. Conversely, if the weight of the displaced water is MORE than the weight of the egg – as it is with very salty water – then the egg will float.

We’re counting down the days to Easter! We hope you’re just as excited as we are. And when we’re excited, we like to get a little crafty! You’ve already met Hoppy Floppy, now bring him to life with this adorable DIY bunny mask. Creating the mask is as easy as 1-2-3!
Here’s what you’ll need: Hoppy Floppy mask template
Elastic cord or yarn
6 pipe cleaners (optional)
2 cotton balls or pom poms(optional)
Step 1: Download the Hoppy Floppy bunny mask template. Print out on cardstock and cut along Hoppy’s face
(don’t forget to cut out the eyes so your little bunny can see!)
Step 2: Punch holes on either side of Hoppy’s face as marked, and thread the elastic cording/yarn through. Secure with small knots.
Step 3: To give Hoppy a little more personality and pizzazz, glue three-inch pipe cleaners onto the mask for whiskers, and then glue small cotton balls (or pom poms) over the pipe cleaners for squeezably chubby cheeks.
Step 4: Proudly show off your Easter mask.
Now that your mask is made, use one or more of the following questions to spark storytelling about Hoppy Floppy. Write your child’s answer on a piece of paper and have him or her illustrate it.
• What does Hoppy Floppy do for fun?
• Where does Hoppy Floppy live?
• What do you think Hoppy Floppy is going to do on Easter?

Why would anyone want to put an egg in a bottle, you ask? Nancy B has the answer! A chemistry experiment and physics demonstration all rolled into one, The Egg in the Bottle Egg-speriment is a fun, hands-on way for kids to learn just how powerful air pressure can be!
Want to try it yourself? Here’s what you’ll need:
• A wide-mouth bottle (or flask)
• Hardboiled, pre-peeled Eggs (Medium sized – not large or XL)
• Wooden stirring rods (candles or matches are fine too)
• Laboratory glasses
• And most importantly: Adult supervision!
Tackle the experiment in four easy steps:
1. Place a peeled, hardboiled egg on top of the bottle. Notice that the egg does not move because the air pressure is equal on the inside and the outside of the bottle.
2. Light your match, candle or stirring rod and drop it into the bottle.
3. Quickly place the egg on top of the opening (with the smaller end on top of the opening).
4. Observe how the egg reacts as the temperature of the air changes inside of the bottle. The egg should be jumping up and down as the air molecules escape. POP!! Faster than you can say “Egg-cellent”, your egg is pushed into the bottle!
How did this happen? And how do you get the egg OUT of the bottle? Make sure to watch the video to find out!

Irish or not, St. Patrick’s Day can be loads of fun for kids, and, since spring is right around the corner, it’s also a great time to get outside and explore. Check out these good-as-gold St. Patrick’s Day activities and games: follow the after-school schedule or choose the St. Patrick’s Day game your kids will like best!
Go for Gold
A St. Patrick’s Day game such as a scavenger hunt is a great way to burn off that after-school energy! Make a list of everyday objects you’ve hidden around the house or yard and challenge your child to find them. Add a twist by tasking the kids to find “something green” and “something gold”. Be sure to include the proverbial pot of gold (a pasta pot will do in a pinch, and yes, we know that’s a pot of silver) at the end of your search filled with a fun St. Paddy’s Day surprise—a few coins or candies.
Arts & Crafts, Celtic Style
For this St. Patrick’s Day game, search for a shamrock template online, print, and cut out a master. Then let the kids loose with green construction paper, glitter glue, and markers and watch as your home begins to sparkle like the Emerald Isles. Older kids can even make shamrock garlands! Once the shamrocks are dry, use them for shamrock hopscotch or a good old fashioned game of hot lava.
Read All About It
Your local library is a great place to pick up some Irish folk tales or St. Paddy’s day stories. And while that pot of gold at the end of the rainbow may only live in fairytales, your kids will get a kick out of learning how real rainbows form. Take discovery to the next level and create your own rainbows using a prism at home.
Unicorn & Leprechaun Hide & Seek
Turn a traditional game of hide-and-seek green with Rainbow Prancers & leprechauns! Players start by choosing one “Rainbow Prancer” unicorn. (If you’ve got a Rainbow Prancer Puppet-on-a-Stick, be sure to give it to the unicorn player!) The unicorn hides and the rest of your little leprechauns search for him or her. (If your crew created shamrock art, pin one to each player’s shirt to identify them as leprechauns.) As each player finds the unicorn, they quietly join her and become unicorns, too! The St. Patrick’s Day game continues until the last leprechaun joins the herd of unicorns.
Cheers to a St Patrick’s Day full of fun, luck & a little magic!
