Disguise your jump drive in a rubber toy

Man oh man, there are a lot of crafty techy people out there.  A couple of nights ago I kept looking at all the ways that people disguised their USB drives.  There are plenty of DIY instructions to make Lego USB drives, Chap Stick USB drives, and even mini Cooper USB drives. With all those cute DIY drives out there, I thought I'd try my hand at making my own too.

Since we don't own many power tools (and if I'm going to be honest, I'm quite ill-equipped to use them since I'm dangerously clumsy) I ended up going the easy route.  I disguised my USB drive inside of a rubber frog toy.  So the only "tool" I used was an exacto knife.  

"Ribbit, ribbit!  Feed me data!" 
Keep on reading to see how I made this little guy...

Make your own gummy candies

Did you know that you can make your own gummy candies?  I didn't know that it could be done so easily until I saw this fruit juice gummy candy recipe on Instructables. 

Last week I roped my sister into trying the recipe out.  Using just four ingredients, we made homemade gummy candies in a  little over an hour.  Here are our results:

Ingredients:
  • 2 envelopes of Knox Original Unflavored Gelatine
  • 1 tablespoon of sugar (or more if you want them sweeter)
  • 1 C of juice
  • Canola oil

Directions:
1.  Combine gelatine, sugar, and juice in a pot.  Let the mixture sit there for a minute.

2.  Lightly oil your mold.  (If you skip this part your gummy candies will break apart as they pop out of the molds.)

3.  Bring the mixture to a boil.  Let it boil for 10 minutes.  The liquid will become more viscous.

4.  Spoon the hot liquid it into your molds.
 Notes:
  • I placed my mold on top of a plate before I did this to catch my spills.
  • I had some extra liquid, so I lined a glass baking dish with saran wrap and then poured the liquid into that.  Once the liquid hardened, it was easy to pop out a very large gummy candy.  
  5.  Put your mold into the fridge until your candies harden.  (Mine took about 1 hour to solidify.)

6.  Pop your gummies out and enjoy!

Can you believe that the recipe worked?  I was super stoked because the resulting gummies had a great texture and easily slid out of their molds.  I also liked that they weren't too sweet.  Next time I'll probably try using fruit juice concentrate instead of juice (as recommended by the original recipe.)  That should give them a more intense flavor.... and maybe they'll taste more like the store bought ones.

Happy Wednesday!

Make Borax Crystal Flowers

Why make borax crystal flowers?  Well, do you love the look of freshly cut flowers sitting in a vase?  I do.  But I never buy them because of my cursed black thumb.  While most people's cut flowers last for weeks, mine always start turning brown and wilting within a day or two.

Boo, black thumb!   

Last week our craft store had a sale on fake flowers.  I was so tempted to buy them, but they looked kinda cheesy and screamed, "I'm fake and I attract dust."

But I ended up getting the flowers anyway, because I wanted to make something pretty with them.  Here's what I came up with:  Crystal Flowers

Blowing up balloons with baking soda and vinegar

Did you ever make homemade volcanoes as a kid?  I made one in elementary school and remember being amazed by the chemical reaction.

A week ago Chuck and I played around with that classic baking soda and vinegar combination.  But this time, instead of making a volcano, we blew up some balloons.

(Note:  I can't take credit for this idea at all!  I saw in on Pinterest and then found some really clear directions on Mom to 2 Posh Lil Divas.)

Materials:
  • Balloon
  • Plastic bottle
  • Funnel
  • Vinegar
  • Baking soda
  • Food coloring (optional)
  • Chopstick (optional)

Directions:
1.  Fill your plastic bottle a little less than half way with vinegar.  (I added some blue food coloring so we could see the reaction better.)



2.  Using the funnel, fill your balloon half way full with baking soda.  (If your baking soda is full of clumps, like mine, a chopstick will help to break those up so the baking soda falls into the funnel.)


3.  Attach the balloon's mouth to the bottle, but don't let the baking soda pour out just yet.



4.  When the balloon is attached the bottle, empty out the baking soda and watch the reaction unfold. The combination of vinegar and baking soda will bubble up, and the gas released from the reaction will blow up your balloon!


Balloon magic!

Make a sailboat out of a shampoo bottle

((Thank you to everyone for entering my Kiwi Crate Giveaway.  Before I talk about today's crapt, let me just announce that the winner of the giveaway is Mel!  Congratulations!  Please email me your mailing address so I can send you a Kiwi Crate straight away.))


Hi everyone!  Today I'm going to share how I made this shampoo bottle sailboat after being inspired by this DIY boat kit found here:

Materials:
- empty shampoo bottle <-- crap!
- 2 rubber bands
- wine cork <-- crap!
- drill
- stirrer <-- crap!
- straw <-- crap!
- pair of scissors
- triangle from a potato chip bag <-- crap!
- tape (packing tape is best, but I only had clear plastic tape)

Here are the boat's main components:

Directions:
1.  Cut your cork in half lengthwise.  Then, drill a hole through the middle.  The hole should be big enough to hold your stirrer (aka the mast) up.

2.  Your straw is going to be the horizontal bar holding up your sail (aka, the boom).  Cut your straw to the desired length.  Then, make two triangle cutouts on each side of the straw, so that your stirrer (aka the mast) can slide into the straw.  Both your stirrer and straw will support your plastic bag sail.  





3.  Cut your plastic chip bag into a triangle sail shape.  Tape the plastic bag onto your stirrer and straw to create a sail.



4.  Use two rubber bands to attach your cork to your shampoo bottle.  Then, stick your stirrer into the cork's hole and voila, instant sail boat.

The boat sails nicely in your bathtub, but Chuck and I took it one step further and sailed the high seas (eh hem... a nearby lake.)  We just tied a ribbon to it so that it wouldn't float away.

Hope you and your little one enjoy this crapt!

Make pipe cleaner bubble wands and big bubbles

Currently Chuck only knows a couple of words.  One of them happens to be "bubbles."  This kid of ours really loves bubbles.  He'll point outside and say "bubbles."  He'll point to round objects and say "bubbles."  He'll point to the bathtub and say "bubbles."  He'll even point to birds and say, "bubbles."

Given his obsession with soapy spheres, I thought it would be fun to make our own bubble wands and bubble solution.  These pipe cleaner and straw wands make larger bubbles than the wands you typically buy in the stores.

To make the straw and string wand:  String together two straws with some yarn.  Slide the knot into one of the straws. If you have problems getting the string through the straws, try sucking it through.  You'll get a mouthful of string, but it works!
We dunked these wands in our homemade bubble solution and had some messy fun. At first it was difficult to make the larger bubbles, but I soon got the hang out of it and created some lovely large spheres.

(Psst- Here's the recipe for the bubble solution that we used.  I combined 5 C warm water, 1/2 C Dawn dish detergent, and 1/4 C glycerin.  I gently mixed the liquids together and made sure not to create suds.   Then, I let the solution sit overnight.   Even though this recipe made fairly large bubbles, I really didn't like the way the Dawn smelled.  Yuck.  Plus, Chuck tried to rub his face with soapy hands, so I worried that the soap stung his eyes.  Next time I'll find a recipe using baby shampoo.  This way the solution won't smell so detergent-y and Chuck's eyes won't sting.  )

Here are some photos from our first big bubble making adventure:



I found that the bubbles didn't pop as quickly if I made them by moving the wand through the air instead of blowing it.

Another bubble created by the wind.   


All in all, not a bad start.  We managed to make large bubbles, but they popped really easily.  Hrmm... Next time we'll try a different solution and we'll make one of those giant bubble blowing wands.  Oooh! I can't wait!

Make a bubble snake

We don't drink much soda so when hubby finally brought a Pepsi home I snatched up his empty bottle quicker than a hungry child grabbing at freshly baked Christmas cookies.

Why?  Well, I had been dying to make a bubble snake blower. And honestly, could you blame me?  Look at the long foamy chain of bubbles I was able to blow.

Wowzers.  This photo makes my inner child squeal with delight

To blow awesome foamy snake-like bubble chains, I just needed a couple of materials:

Materials:
- empty plastic bottle
- wash cloth
- scissors
- rubber band
- dish detergent
- water
- plastic container

Directions:
1.  Cut off the bottom of the bottle.
2.  Cut a circle out of the wash cloth that's about 1-2 inches larger than the bottom of the bottle.
3.  Use a rubber band to attach your washcloth circle to the bottle.  That's it!
4.  Dip the bottle (wash cloth bottom) into dish detergent that's been mixed with a bit of water.
5.  Blow.  A foamy bubble snake will appear before your eyes.

(Warning:  Do not inhale, only exhale. Otherwise you'll end up drinking dish detergent like I did. Yuck.)

Here are some photos of Baby Chuck and I playing with our bubble snake blower.  (You may be wondering why we're in the bath tub.  Or why my bathtub is so dirty.... Hmm..  Well, we fully intended to blow bubbles outside, but it was just too cold.  The bath tub served as a nice place to try the activity out, since the bubbles created quite a sticky mess on the ground.  As for why my bathtub  is so dirty... I've neglected to clean it.... eek.)




Let me know if you try this out with your kids.  I can't wait till the weather gets warmer.  We'll definitely try blowing more bubble snakes outside.
