Experiment of the week: Bubbles

Here is a challenge perfect for summer - which solution makes the best bubbles: Homemade or Store-bought?  It is an age old question on so many fronts. Here you need:

Your favorite store purchased bubbles
Bubble wands or pipe cleaners made into wands
Homemade bubbles (my recipe to follow)

So, what makes a good bubble? Does it last the longest? Is it the biggest? or the most?  Decide a head of time and make a prediction (guess) about what solution makes for the best bubbles.  Now test! Remember to use the same bubble wands for the testing and go for it!

My favorite bubble recipe:
1 gallon of water
1 9oz bottle of Dawn (any color)
2 oz glycerin
24 hours

Mix the water, Dawn and glycerin together very slowly and set aside for a day. Makes gobs of bubble solution that can last for months. If it is possible not to use it all up in a day!

Fun Friday Fact

Could dinosaurs spit?

In the movie Jurassic Park, a Dilophosaurs spits venom in a man's face. Alas, there is no physical evidence that dinosaurs could spit. It takes a lot of muscle to spit and that probably would have left marks on the skeletons of dinosaurs.

There are snakes such as the Spitting Cobra that appear to spit venom, but they really just spray their venom. The have large muscles that allow them to eject venom quite accurately.

Check out this video of a spitting cobra, well spitting. It is under two minutes and very well done.

Dirt!

Here are some fun ideas for dirt explorations...

Make Mud Bricks: Add a small amount of water to different kinds of dirt and dirt with sticks or leaves. Pack in to a brick mold or some sand toys. Let them dry in the sun for a day or two. Make some predictions about which bricks will be the strongest?  How could you test your idea? Unmold them and test your ideas.

What is in the dirt? Put dirt in a kitchen strainer and pour water thru it. What happens?  What stays and what goes thru?  Now put a coffee filter in the strainer and do the same thing. What is left behind now?

Erosion: Make a mountain of dirt and slowly pour water over it. What happens?  Make your mountain again. What would happen if you poured water quickly or in a different place?

Growing: Do a dirt scavenger hunt in your yard. Gather up some pots and put different kinds of dirt in to each pot. Then put in a seed or plant and see which soil is best for growing plants.

Eat Dirt: Make chocolate pudding and sprinkle the top with crushed chocolate cookies or chocolate graham crackers. Add some gummy worms and you have dirt for lunch!

Experiment: Water Tension

I have a challenge for you. Fill a glass of water right up to the top. Guess how many paper clips can you put into the glass before the water spills over. Will it be 5 or 10?  Does it matter if you slide them in or if plop them in?  Keep filling the glass with paper clips - the girls scouts just did this and were able to add a whole lot.

Refill the glass and see you can float a paper clip on the top of the water.  It is far trickier than you'd think.  If you really get stuck, use a fork to lower it down onto the surface.

Museum Review: Dinosaur State Park, CT

Dinosaur State Park in Connecticut needs to be on your list of places to go with kids. Go, right now, and put in on your list.

I'll wait.

This is just over an hour from our house and we left very early in the day to be there for their 9am opening. We arrived before the gift shop opened. As you enter the big silver dome, be prepared, you go through the gift shop that has lots of cool goodies low to the ground.

The exhibits are very well thought out and combine interactive button pushing and lever lifting with a compelling story of how the foot prints were discovered and protected. There are plenty of things to touch and some great explanations of different rock patterns. This is followed by some great short films about how the tracks were made and preserved. I especially enjoyed the interactive exhibit on the patterns of the tracks.

Then you finally get to see the actual tracks. It was quite impressive.

A small room at the end contains some of the best stuff. This room is devoted to kids with magnetic dinos on posters, puppets, stencils, fossils with guides, books, CTs of dino eggs, coloring, stamping, and live animals. They do have live animal talks from time to time but we didn't stay to see them.

They had a film about dinosaurs in claymation. I found it deeply irritating because they gave human emotion and motivations to the dinosaurs. Really?!  Don't bother with that film. There were other films later in the day. Hopefully they are better.

Be sure to ask for a Bingo sheet and walk around the grounds. There are plenty of picnic tables and gorgeous trails. There is a place to make your own casts too but it wasn't open - perhaps the crack of dawn was too early! or it was too chilly.  A small open air theater, butterfly garden and herb garden will be good spots to visit later in the season.

This is a 5/5 star location. The trails were either dry or had board walks so it is easy walking. Strollers would be tricky. Everything is well labeled and the Bingo was a huge hit. Be sure to return it for prizes.

If you aren't sure about what to purchase in the gift shop I recommend the grab bag. It is $2 and has magnetic stones, misc gems, stickers, a pencil and a pencil topper along with a book mark. The gift shop can be overwhelming for its sheer coolness for nerds like me and my kids - so be prepared with a budget.

Bring lunch it is worth staying a while.

And if you geocache, there is a great cache on site.  Is there a letter box??

OT: Slightly

I tried something rather silly and thought that you all might enjoy it. I mailed some spring time goodies to my niece, nephews and my husband's grandmother today. 

Yes, those are plastic eggs. If you grab the large ones - the bigger the better - and fill them with goodies, you can mail them. I filled them with stickers, silly bands, candy and toys. You can fit a whole lot of stuff in those eggs.

I mailed them as small parcels and it took $1.95 in stamps. The meter sticker doesn't fit so I used three pretty butterfly stamps on each one. (No, these weren't the strangest thing my PO has ever mailed - I am so going to have to up my game!)

There are loads of other Messy Fingers-like uses for plastic eggs. Here are a few favorites from our house:

• Noise makers - add beads, buttons, beans etc. and tape really well
• Color sorting - can you match the color of the egg to legos, beads, balls, blocks, etc.
• Play-dough holders - this is a fun container for home made playdough
• Bath toys - they are great for holding various amounts of water
• Bath toys II - put a bath tub dye tab in one with a hole (lots have a hole) and toss in the tub

How do you like to re-use your plastic eggs?
