12 Sep

Augmented reality just got real…

More than quick, it will take you around 5 minutes to make each filter!

You`ll need:

_Acetate. You could get A4 sheets from an art shop or even recycle the transparent film of  a  product`s packaging.

_Permanent marker (s).


How to make your photo filters:

1. Cut a few acetate squares or rectangles; if you`re using an A4 piece, you could divide it in 4 pieces.

2. Draw funny things to add to your photos, like wigs, hats, mustaches… get creative.

3. Shoot!

34_The Imagination Box

7 Sep

So… if you´re the kind that likes to play with the box rather than the toy, keep reading.. this one´s definitely for you

© 2011 Fernanda de Uriarte

Probably one of the easiest ones; not the quickest just because you have to let it dry overnight.

You`ll need:

_A cardboard box, maybe from a large appliance or from moving places.

_Water-based blackboard paint and a brush (You´ll find the paint in art shops and some paint shops)

_Old newspapers, recycling paper or a plastic mat/bags to cover the surface where you´ll be painting.

_Masking or parcel tape to secure the bottom of the box.

_Coloured chalk to imagine and transform your box over and over again.

How to make your imagination box:

1. Close the bottom of the box and tape it so that it doesn’t open again.

2. Paint the box with the blackboard paint, including the flaps to open it and close it. Remember to cover the surface where you´ll be painting with cardboard, plastic bags, etc.

3. Leave it to dry for a few hours. If there are spots that look a bit “washed out” add an extra layer of paint over those spots.

4. Leave your box to dry for 24 hours or as long as the packaging of the paint suggests.

5. When the box is fully dry, get the chalk and let your imagination fly.

What about a space ship?

What else could your box be… A monster perhaps?

What about a house or a diver suit?…It could be whatever you imagine.. that´s the point!

(When you´re ready to transform your box into something else, use a DRY tissue or cloth to erase the chalk (remember, the paint is water based so if the paper or cloth is damp, you´ll take the paint away))

33_Fridge Hangman

6 Sep

Now you can play this classic word game while deciding what to have for breakfast (oooor lunch, or dinner, or just a snack, or just because….)

© 2011 Fernanda de Uriarte

This one´s super quick, super easy and super fun…It´ll take you 30-40 minutes tops.

You need:

_2 A4 pieces of magnetic paper (you can find it in any decent art shop, they might also call it magnetic printer paper)

_Coloured markers or crayons

_Pen or pencil


_Cutter or Exacto knife and cutting mat (or a surface that is safe to cut on).

_Black marker.

How to make your Fridge Hangman:

1. Trace a grid on both pieces of magnetic paper. Draw the lines of the grid about 3cm apart from each other. When you finish tracing the grid, you´ll have lots of 3×3 cm squares.

2. Draw the “hanging platform” in a space about 2×3 squares. Draw the head, body, legs and arms in different squares.

3. Fill all the other squares in with the alphabet. Pick different colours, make some capitals, and repeat the alphabet as many times as you can. You´ll have a few squares left; write more vowels.

4. Draw a thin black line along one of the sides of each piece of magnetic paper. These will make the “blanks”.

5. Use the cutter and ruler to cut all the squares.

6. Cut the man and platform as well as the “blanks”

7. Put everything on the fridge and done!

Perfect way to practice your spelling and learn new words.

32_Invisibility Box

6 Sep

A magician is not supposed to reveal his tricks, but this time I`ll make an exception … wanna know how to make your hand (or anything really) disappear?

It´ll take you around 2 -2 1/2 hours to make your invisibility box.

You´ll need:

_A border-less mirror.

_Mount board or any other type of thick cardboard (about 2-3 mm thick). I used  black cause we´re doing magic! but you can choose any colour you want.

_A piece of acetate.. It could be that you recycle a plastic packaging or something similar. I actually used the pack of my mirror.

_Double sided tape.



_Cutter and cutting mat or a surface to cut on.

_Coloured tape to cover the edges if they don´t look that nice (that´s the downside of using black: every little detail shows!)

_You might need a bit of maths skills for this one, but nothing to worry.. I`ll show you what to do.

How to make an Invisibility Box:

Before we go to the detailed instructions, let me explain a little so that you what I`m talking about all the way through:

The invisibility box works by placing a mirror diagonally inside the box. That way, you get half a box “obscured” from the view of your public and the mirror does the trick by creating the illusion of looking at the whole box through the window at the front. When you put your hand or any other object inside the box you fill the “obscured” part of the box, and because of the mirror illusion, it looks as if your hand was disappearing as it goes inside.

It will be hard for us to find exactly the same size of mirror, that´s why instead of giving you exact measures, I`ll show you how to figure out the dimensions of your box, depending on the size of the mirror you find.

Let´s do it step by step:

1. We´ll start with the maths (yaaay!).

The mirror will be placed at 45º inside the box. That means that the height and depth will have the same dimensions. We`re using Pythagoras theorem to calculate the sides of a right triangle (the sides of the triangle will be the sides of your box). I have simplified and written the formula for you to replace the letters with the right numbers.

The width of your box is the same as the width of your mirror.

Check the diagrams below:

2. On the mountboard/cardboard, draw a rectangle the same length and width as your mirror and add about 4 cm. to both ends, lengthwise (8cm. total)

3. Cut the rectangle, including the extra 8 cm; pass the cutter a couple of times of the lines dividing the original rectangle from the extra length, make sure not to cut all the way through.

4. Bend these extra length bits back.

5. Put some double sided tape on the back of your mirror and stick it to the piece you just made.

6. Once you’ve figured out the dimensions of the box, draw a net, on the mountboard/cardboard to make the actual box. (check this posts out to see a few examples of nets so you know how to make yours camera obscura, Spyscope, cubic Transformers). Make sure you make 2 openings: 1 for your hand and other objects to go in and another one to let your audience see the trick; I`ll call the later “the window”.

7. Cut out and score (pass the cutter without going all the way through) where needed.

8. Cut a piece of acetate the size of the window plus 5mm on every side. So, if for example, your window is 10cm x 10cm, your piece of acetate will be 11cm x 11 cm.

9. Use some tape to attach the piece of acetate to the window, on the side that will go inside the box.

10. Stick some double sided tape to the tabs (extra bendy bits of your box-to-be)

11. Start folding and sticking the whole thing together. Don´t close it yet! we still have to put the mirror in.

12. Remember the cardboard piece with the mirror from the beginning? Get it and stick it with the mirror facing down and towards the acetate window. (check the image below)

13. “Close” the box.

14. If you like, you can use the colour tape to cover the white/not so nice edges and make your box all black and nice.

Invisibility box ready to do the trick!

Just stick your hand in and watch it disappear in front of everyone’s eyes.

You could also do it the other way around… hide something inside the box and make it appear when you take your hand out.

And remember… a magician never reveals the trick.
